Is that karma?



今天和一个SB姓丁的同事争论美国选举,她真是无知的蠢猪一头,而且是一只只会在床上被干的嗷嗷叫的母猪一头。她就是现在中国所谓高学历的代表,还在叫嚣课本上的老观点“美国选举是被少数大财团和资本家控制的浪费纳税人钱的游戏”。她的一副只顾她一亩三分地,不顾他人死活的嘴脸,只想让别人流血换回她利益的龌蹉心态让我立即想起了3件事情。


1,         我顿时想起了老江在接受CNN记者华莱士采访时被问到中国为什么不实行民主选举时回答说“中国人素质太差,不适合民主选举”。我不得不佩服老江同志的敏锐洞察力看穿了中国人的本质,都是这种货色的SB,中国目前的确不适合民主选举。最后的结果中共倒台了,但是也没有迎接到普选,一个王朝倒下去,另一个山大王站出来,改朝换代而已。我现在倒不希望中共那么快死了,如果它一旦死了,这些十多亿如此是非颠倒,黑白不明的中国人到底该咋办呢?
 

2,            Dawkins给出的解释为什么生物体要参与“瓶颈”般的生命循环,将一个螺旋桨发动机如何改成喷气式发动机呢?你做不到,你必须抛弃螺旋桨风发动机,回到绘图板上重新来。有些人一辈子都是不可能清醒的,他唯一能做的只有死亡,历史的车轮会无情的压过她的尸体前进。我但愿她的女儿不像她一般愚蠢至极,思想上的进化太难了,赶紧死吧。

3,              我原谅sharon stone 说的Karma的言论了,because she is right.这样的人死的越多越早,中国进化的越快。她要活到80岁,哪给影响多少人啊?就像朝鲜人民广场上誓死保卫金正恩的SB一样,他要死,就让他们死好了。

愚蠢的中国人只关心家以下国以上的事情,成天抱怨孩子不争气老公不上进,要不就是脖子上挂着佳能的相机喊口号“保卫钓鱼岛”,回家也不学习,天天看着电视上抗日战争的武侠神剧的民族,这样猪一般的民族谈什么“中国梦”?呸,狗屁,我看是“中国噩梦”。欧洲的“安全屋”根本不适合中国,因为安全屋是文明的产物,而中国人还处于弱肉强食的畜生的轮回中没有走出来,如果真的有安全屋,我都想只撒播我的基因,而不用付出任何代价,更别说其他中国人了。“计划生育政策”一直是西方诟病中共人权的一个把柄,但是我真的要为伟大光荣正确的党国叫屈,“太冤了”,西方人真的是不懂中国,如果中共现在就放开生育,凭着现代化的医疗手段的胎儿高成活率和中国人原始动物般撒播基因的欲望,地球都会被中国人压塌的。非文明的中国人只能是由流氓的中共才能治的了它。我反而认为“计划生育政策”是中共做的唯一对的决定,你想想当所有女人都只和习总繁衍后代的话,下一代都变成官二代,灭了谁都不是,这样才能真正在一个平台上博弈。

亲爱的美美们,加油吧,向官二代红二代进攻吧,繁殖出三代来,这没有什么可耻的,反正你被谁干都是干,为什么不挑一个性价比高的呢??她的丫头以后痛苦的日子还在后面的。上学送礼,学业压力,就业男女歧视,等着吧,好日子等着她呢。By the way,我是不会把我的基因撒播在这片罪恶的土壤上。

What are the genders?


I saw the news, according to Reuters - Several hundred thousand opponents of same-sex marriage marched in central Paris on Sunday. I did not expect that the French people who are so romantic nation actually value the genders so much. The Nation, who owns the Charles de Gaulle the greatest man in human history, loses the past glory immediately in my heart. It reminds me that the vast majority of people are always stupid in human history, whatever in west or east. So today, I want to have a look at how we define the female and male, and what exactly control the sex determination. 

All living things reproduce. Reproduction is the process of generating offspring. There are only two types of reproduction: sexual and asexual, whatever animals or plants. Here I am not going to see the differences, advantages or disadvantages of sexual and asexual reproduction, and this chapter only focuses on how sex determination. 


1Apparently, higher organisms have resorted to sexual reproduction in spite of its complexity, although sexual reproduction involves more time and energy.   Most animals and some plants have two genders, and sex-determining mechanism in different types of organisms is a big difference. How is gender determined in an organism? It is actually determined in different ways. It is broadly divided into two main categories: temperature-dependent sex determination (TSD) and genotypic sex determination (GSD).

TSD: Precisely speaking, the temperature-dependent sex determination is just one of the non-genetic sex-determinations. Many other sex-determination systems exist. In some species of reptiles, including alligators, some turtles, the tuatara, sex is determined by the temperature at which the egg is incubated during a temperature sensitive period. The temperatures required for the specific sexes are known as the female promoting temperature and the male promoting temperature. When the temperature stays near the threshold during the temperature sensitive period, the sex ratio is varied between the two sexes. For example, in sea turtles, warmer temperatures produce more or all females, cool temperatures produce more or all males, and the pivotal temperature is the constant incubation temperature that produces equal numbers of males and females. TSD also occurs in other reptiles (crocodilians, some freshwater and land turtles, some lizards), some types of fish, some types of invertebrates, etc.
In TSD animals, how do we define the genders? Apparently, the only way we define it is depending on sex expressive traits, because the same genders may not share the same sexual genes.
GSD: Genotypic sex determination occurs when sex is established by genetic factors (e.g. sex chromosomes) at conception and it has two main types: XX/XY and ZW/ZZ. The XX/XY sex-determination system is the most familiar, as it is found in humans. In the system, females have two of the same kind of sex chromosome (XX), while males have two distinct sex chromosomes (XY). The XY sex chromosomes are different in shape and size from each other, unlike the autosomes. Some species (including humans) have a gene SRY on the Y chromosome that determines maleness. The ZW sex-determination system is found in birds, reptiles, some insects and other organisms. The ZW sex-determination system is reversed compared to the XY system: females have two different kinds of chromosomes (ZW), and males have two of the same kind of chromosomes (ZZ). In the chicken, this was found to be dependent on the expression of DMRT1. In birds, the genes FET1 and ASW are found on the W chromosome for females, similar to how the Y chromosome contains SRY. However, not all species depend upon the W for their sex. Because the use of ZW sex determination is varied, it is still unknown how exactly most species determine their sex. I roughly agree that God always finds a way, when he determines to do something.


In XX/XY system, Y chromosome evolved from X chromosome, in contrary in WZ/ZZ system, W evolved from Z chromosome. In the history of long evolution, some genes on Y and W chromosomes have been partially degradedso Y or W chromosome can’t synthesize the normal sex organ independently.

In GSD animals, how do we define the genders? If you think the one who has penis is a male, what about the birds with WZ chromosomes and fish? There is no big difference between two sexes, because neither sex has penis. Birds choose cloaca kiss to fertilize, and fish basically are in vitro fertilization. Even in mammals, you can not easily define genders.
2Next, we are going to see some special examples in mammals which people call as abnormality.

Freemartin:


A freemartin or free-martin is an infertile female mammal which has masculinized behavior and non-functioning ovaries. It is genetically female, but has many characteristics of a male. The ovaries of the freemartin do not develop correctly, and they remain very small. Also, the ovaries of a freemartin do not produce the hormones necessary to induce the behavioral signs of heat. The external vulvar region can range from a very normal looking female to a female that appears to be male. Usually, the vulva is normal except that in some animals an enlarged clitoris and large tufts of vulvar hair exist. In short, these animals often have a masculine steer-like appearance, but with XX chromosomes.

The cause of this disease is, in most cattle twins, the blood vessels in the chorions become interconnected, allowing blood from each twin to flow around the other. If a fetus has XX chromosomes, the lack of testosterone production during gestation will allow her to develop female external and internal genitalia. Male animals develop differently in the womb because their XY chromosomal arrangement causes them to produce testosterone. This hormone inhibits female reproductive tract development. When mixed sex twins are developing, it is possible for the blood vessels within the two placentas so fuse and form a common circulation. When this happens, the testosterone produced by the male calf is able to circulate to the female twin and affect her sexual differentiation. If both fetuses are the same sex this is of no significance, but if they are different, male hormones pass from the male twin to the female twin. It also occurs occasionally in other mammals including sheep, goats and pigs.

The key word: the twins shared the same placenta and the female one was affected by the testosterone from the male one. I guess if a fertilized egg was injected by outside testosterone from the beginning, the female babies always have masculine vulva. In other words, if male really has a uterus, is he appropriate to have a baby? I do think scientists also can create artificial freemartin human. You could say I have a daydream, but I have another perfect evidence to support my daydream - Spotted Hyena.
Spotted Hyena


The female Spotted Hyena's urogenital system is unique among mammals: there is no vagina, and the clitoris is as large and as erectile as the male's penis - only the shape of the glans makes it possible to tell the sexes apart. In the case of female spotted hyena, the vulva is fused, and the clitoris is used for urination, mating (when the clitoris contracts, while the opening widens to allow penetration) and giving birth. When spotted hyaenas mate, the male inserts his erect phallus into the female's flaccid one. Another curious fact about female spotted hyenas, which scientists have confirmed, is that they carry higher levels of testosterone than the males in their blood, and this is something that can be observed as early as the embryo stage. That's why biologists initially believed that the development of the clitoris was caused by the huge quantities of testosterone to be found in the fetus.

The key words: female spotted hyenas have higher levels of testosterone than the males and the baby girl who lived in the mother’s body like this must inevitably be led to masculine vulva. This point can be understandable. In long history of spotted hyena evolution, she has already known how to get along with that external factor in peace and evolved a special reproductive system under that. I think we can do an experiment like this: have an artificial insemination spotted hyena, and then put this zygote into normal dog’s uterus, and see what the female baby dog’s vulva looks like? We will know whether it is affected by mother or not? I bet the little female dog is goint to have a normal feminine vulva, but infertility. The influence from mother to child or between the twins is not just limited to the sex hormone, and they also can exchange the cells.
Chimera

Here I don’t want to talk about "chimera" in Greek mythology where it means a monster: part goat, part lion, part snake. In human biology, a chimera is an organism with at least two genetically distinct types of cells -- or, in other words, someone meant to be a twin. But while in the mother's womb, two fertilized eggs fuse, becoming one fetus that carries two distinct genetic codes -- two separate strands of DNA. 

So far the case of Lydia Fairchild is the most famous case in U.S., and it turned out she's a chimera which is a fusion of non-identical twins, and the best thing of this case is to make lots of researchers started to pay attention to chimera on human. Here I have another big question: where are the non-identical twins from? Apparently, chimera must be a fusion of non-identical twins, and there is no cells exchange problem in identical twins, because no matter they exchange the cells or not, they always share the same genes, and you can’t find out. What about fraternal twins? But fraternal twins each have their own placenta and own amniotic sac, two different placenta means they both directly exchange everything with the mother, and two different amniotic sac means they don’t have any chance to exchange anything to each other. I think the fraternal twins are very hard to fuse together, so we can easily find that those conjoined twins are identical twins, at least so far we don’t find any conjoined twins are from traditional fraternal yet, and I also think the fraternal twins are very hard to affect each other, otherwise we must can find lots of fraternal female twin’s vulva masculinization, due to her brother’s androgens.




In the uterus, a majority of monozygotic twins (60–70%) share the same placenta but have separate amniotic sacs. In 18–30% of monozygotic twins each fetus has a separate placenta and a separate amniotic sac. A small number (1–2%) of monozygotic twins share the same placenta and amniotic sac. Fraternal twins each have their own placenta and own amniotic sac.

Microchimerism (abbreviated Mc) is the presence of a small number of cells that originate from another individual and are therefore genetically distinct from the cells of the host individual. Microchimerism in humans commonly happens during pregnancy. Cells from the fetus' immune system can enter the mother through the placenta, where they may survive and continue to reproduce through mitosis. In some cases, the descendants of these fetal cells remain in the mother decades later. The same process in reverse can result in populations of maternal immune cells living in the fetus, though this is less common. I think as time goes by, microchimerism will be observed in many tissues and organs in our human. Here I want to illustrate that freemartin doesn’t mean she is a microchimerism, maybe her vulva development is just interfered by androgens from her brother, but she is not a chimera at all. I just make a guess, what I want to say is they are not necessary and sufficient conditions. Same logic to Spotted Hyena. I want to emphasize that If the Microchimerism between mother and child really happens generally, I think we should reconsider the surrogacy very carefully.

No matter what type of the twins, they always have to exchange things with the mother, so we can understand the chimera between child and mother, but what about the chimera between the twins? I think we have to know another Interesting case – polar twins.

Semi-identical twins

According to BBC news, Scientists have revealed details of the world's only known case of "semi-identical" twins. Researchers have discovered a pair of twins who are identical through their mother's side, but share only half their genes on their father's side. 

Researchers investigated the twins' genetic makeup because one was born with ambiguous genitalia. This twin turned out to be a 'true hermaphrodite', with both ovarian and testicular tissue. The other twin is anatomically male. Genetic tests revealed that each twin contained some 'female' cells with two X chromosomes, and some 'male' cells with an X and a Y. The proportion of each type varies from tissue to tissue in each twin, the researchers report in Human Genetics. So scientists gave the explanation is that the 'semi-identical' twins are the result of two sperm cells fusing with a single egg — a previously unreported way for twins to come about, say the team that made the finding.

Frankly speaking, I do not agree with the interpretation like that. The explanation they gave depends on two evidences: one is the twins both are chimaeras, and the other is one of the twins was born with ambiguous genitalia and turned out to be a 'true hermaphrodite' with both ovarian and testicular tissue. I think these two points are insufficient to support the conclusion they gave. Here I can give you another story depending on these two points.


We have to recall Meiosis first. In humans (and most vertebrates), the first polar body does not go on to meiosis II, but the secondary oocyte does proceed as far as metaphase of meiosis II and then stops. Only if fertilization occurs will meiosis II ever be completed. Entry of the sperm restarts the cell cycle. In principle, polar bodies are fertilized by sperm, even if the egg cell and a polar body were both fertilized by separate sperms., further development would usually not occur because the zygote formed by the fusion of the sperm and polar body would not have enough cytoplasm or stored nutrients to feed the developing embryo. The following figure is a normal process of meiosis and fertilization:

One egg × One sperm


I don’t know what the key it is to decide which lucky half can win all cytoplasm and which poor half genes have to dies due to uneven splitting of the cytoplasm, but I believe competition is everywhere. Once the game is evenly matched, the first polar body also gets some cytoplasm as much as secondary oocyte. The following figure is an even splitting during meiosis I, but uneven splitting during meiosis II. Due to the two sperm are random, so they share 50% identical genes to each other. Don’t forget homologous chromosomes segregate from each other during meiosis I, so the two eggs share 0% identical genes. The result is the twins share no genes on their mother's side, but only half their genes on their father's side. Maybe we can call them “Quarter identical twins”.


Two eggs(share 0% identical genes) × Two sperm(share 50% identical genes)




The following figure is an uneven splitting during meiosis I, but even splitting during meiosis II. Due to what happened is just sister chromatids are separated during meiosis II, and the two sperm are still random, so the result is the twins share the exactly same genes on their mother's side, but only half their genes on their father's side. Maybe we can call them “Three quarters identical twins”. Since it is very difficult to separate the two daughter cells during meiosis II, so zygote A and zygote B share the same placenta, once the twins are different genders, freemartin and chimeras happens.


Two eggs(share 100% identical genes) × Two sperm(share 50% identical genes)


What if both even splitting happened during meiosis I and meiosis II? The four sperm are still random, so the Quadruplets share their 50% genes on their father's side, and zygote A and zygote B is three quarters identical twins, zygote A and zygote C are quarter identical twins.





Four eggs × Four sperm(share 50% identical genes)


Plus identical twins and fraternal twins, here we can get 4 types of twins; the genes share rates are 25%, 50%, 75% and 100%. I think these situations have the name as “Polar body twins”, I do believe it can happen by accident. As polar bodies and the egg can not be properly separated, the polar twins share the same placenta, so they easily become chimeras. If they are different genders, the result is the female one will be affected by the male one in vulva development. My theory to case of "semi-identical" twins is they are just the result of the case of polar twins plus the case of fertilization by different gender sperm. I think it make sense that if they share the same gender, we can’t find them. Whatever traditional monozygotic twins or fraternal twins, they don’t share the 25% or 75% genes. We have found out the 75%, till we find out the twins who share 25% genes: they share no genes on their mother's side, but share only half their genes on their father's side, then we no longer deny the polar twins’ existence. I do think the “Semi-identical” twins which BBC reported is just this result of three cases: three quarters identical twins plus chimera and freemartin.

I think the case of Lydia Fairchild is not closed, we can check the two different sets of genes on her body, and then we can figure out what kind of twins before they fused. Above three examples are female were interfered by the male hormone more or less, but sometimes androgen got the bad luck.

AIS:

Androgen insensitivity syndrome (AIS), formerly known as testicular feminization, is an X-linked recessive condition resulting in a failure of normal masculinization of the external genitalia in chromosomally male individuals. This failure of virilization can be either complete androgen insensitivity syndrome (CAIS) or partial androgen insensitivity syndrome (PAIS), depending on the amount of residual receptor function. In short, these defects make the body unable to respond to the androgens that produce a male appearance.

Human embryos develop similarly for the first six weeks, and the indifferent gonads begin to differentiate according to genetic sex. If the karyotype is 46, XY, testes develop due to the influence of the Y chromosome's SRY gene. This process does not require the presence of androgen, nor a functional androgen receptor. Then in the next process, what if mutation happens in the AR gene and the function of the androgen receptor (AR) is impaired. This gene provides instructions for making a protein called an androgen receptor. Androgen receptors allow cells to respond to androgens, which are hormones (such as testosterone) that direct male sexual development.

Apparently, the example of freemartin illustrates that, due to the exterior strong hormone (testosterone) interference, despite the presence of ovarian, the accessory sex glands still go to the direction of male, but the genotype is 100% sure of XX. Conversely, the example of AIS illustrates that, when the expression is blocked, despite the presence of testosterone, the accessory sex glands still go to the direction of female, but the genotype is 100% sure of XY.


Individuals with CAIS are raised as females. They are born phenotypically female and almost always have a heterosexual female gender identity; the incidence of homosexuality in women with CAIS is thought to be less than unaffected women. Because of this, we can get if the gay genes really exist on chromosomes, it doesn't have any concern with sex chromosomes.

The two examples of freemartin and AIS can apparently illustrate that together, in mathematics, the sexual expression which controlled by gene is a piecewise function. First step, the gonad (testes or ovaries) is synthesized by SRY on the Y chromosome or by some genes on X chromosome. Of course, in mammals, the genes which control the expression of testis are completely dominant genes, compared to the genes which control the expression of ovarian. Second, some specific hormones, released by testes or ovaries, control the growth direction of other accessory sex glands, whether labia fused or not, the clitoris shaft became big and wrapped urethra or not, the gonad descend or not. This two steps both control a person whether abnormality or not step by step.


Here I want you to think how we should define the sex of AIS, depending on the genotypes or expression traits? Do you think it is OK that the person with AIS marries a male, if you are against Gay marriage? 

In GSD animals, how do we define the genders? We should define it depending on sex genotype or expressive traits? If we choose expressive traits to distinguish the two genders, does it depend on gonad, primary sex characteristics, or secondary sexual characteristics? It is very complicated to classify on this issue.

3, Another thorny issue: hermaphrodite

From the view of genes

As long as there are two different sex alleles on your chromosomes, you can be identified as hermaphrodite. In other words, if your sex genes are not homozygote, you are hermaphrodite. In my theory, male with XY chromosomes in mammals and female with ZW chromosomes in birds are all hermaphrodites. The reason, why sometimes testis genes become dominant genes in some species and sometimes ovarian genes become dominant genes in some other species, all depends on the environment of the sex genes, not only the natural environment, but also the genes environment. Apparently, the environment in birds determined that ovarian gene is dominant, but recessive in mammals. Anyway, whatever the environment determined which sex genes is dominant, it doesn’t change they are hermaphrodites from the gene view. XY and WZ are both Heterozygous in sex genes. 

From the view of sex phenotype

Compared to birds and fish with simple reproductive system, mammals have more complicated system. For example the difference between male and female in birds and fish is just in gonad, but no big much difference in the vulva between the sexes, so I think that is why sex reversal always happen on fish. In mammals, because the vulva between the sexes is very different, there is no chance to make sex reversal at all. So I think it can be divided into three different situations. 

Gonad: As long as the testis and ovary both exist, we can call them as hermaphrodite. This case basically can’t happen on animals, but only some plants. Some flowers that contain both sexual flower parts (stamen and pistil) are called perfect or bisexual while those that contain either stamen or pistil only are called imperfect or unisexual flowers, regardless of whether they lack sepals or petals. We can call this case as true hermaphrodite, and I think it can’t happen on human, except for chimera under one condition two different cells in primary gonadal. Flowers with both stamens and a pistil are capable of self-fertilization, which does increase the chance of producing seeds but limits genetic variation. The separation of the male and female sexual organs increases the possibility of outcrossing or cross pollination.

Subsidiary structure: The cases like freemartin and AIS which have the subsidiary structures of the other gender because of some accidents. A genes of XX with female ovarian, but male vulva, or a genes of XY with male testis, but female vulva. How do we define the two genders now? I don’t think we should consider them as hermaphrodite. 

Shemale: Famous shemales are always from Thailand, and most of them were from poor families and injected external estrogen when childhood. As a woman, I have to say some shemales are really pretty, I can’t help myself looking at them. They still have XY male genes, testis, normal male vulva and all normal male primary sex characteristics, but female secondary sex characteristics due to man-made after birth. Injection estrogen from outside only can change the secondary sex characteristics, but can’t change the genes, gonad and other accessory sex glands. How do we define them? Male? Female? Or hermaphrodite? 

Sex reversal

Sex reversal is very common in fish. Fish that can alter their sex are known as successive hermaphrodites. Normally the sex reversal occurs only once. For example, a sexually mature female reproduces and then becomes a male. The ovaries shrink, the fish develops testes, and male hormones are released. These physiological changes also alter the animals’ behavior. New males become aggressive, defend territory, and court females. In China's countryside, occasionally the kind of thing that hen becomes cock happens, but we never heard that cock becomes hen over night. Why? What if in some fish whole life, they don’t have sex reversal? Should we call them as hermaphrodite? Whatever they have sex reversal or not, their genes never change, right? 

4, What are the genders exactly?

What can we learn from above? Do you lose yourself in my words? What is homosexuality? What is heterosexuality? Before we define someone is homosexual or heterosexual, we have to figure out how should define the two genders. What about the birds with WZ chromosomes and fish? There is no big difference between two sexes, because neither sex has penis. Birds choose cloaca kiss to fertilize, and fish basically are in vitro fertilization. Our human can’t even define the genders clearly, not to mention homosexual or heterosexual. Homosexuality is simply a false proposition.

Richard Dawkins wrote his opinion about genders in his book - The selfish gene “We simply accepted that some animals are called male, and others female, without asking what these words really meant but what is the essence of maleness? What, at bottom, defines a female? We as mammals see the sexes defined by whole syndromes of characteristics - possession of a penis, bearing of the young, suckling by means of special milk glands, certain chromosomal features, and so on, These criteria for judging the sex of an individual are all very well for mammals but, for animals and plants generally, they are no more reliable than is the tendency to wear trousers as a criterion for judging human sex, In frog, for instance, neither sex has a penis. Perhaps, then, the words male and female have no general meaning. In gene’s long journey down the generations therefore, an average gene will spend approximately half its time sitting in male bodies, and the other half sitting in female bodies.”

I do think our humans like to classify too much, fat and thin, high and short, white and black, man and woman, but we really ignore something very rare – true love. In long history of evolutionary: sexual reproduction showed up first; then penis intercourse, we have to admit that until now there some animals on earth that can reproduce but no penis intercourse, like IVF in fish or cloaca kiss in birds; and then marriage, until now I don’t think not every marriage is because of love, especially in patriarchal society, the purpose a woman get into a marriage is for survival, because women can’t go to school like boys, can’t go out to work like man, but only marriage for living; finally love, to be honest, I do not think love is necessary in evolutionary. The only purpose of non-human having intercourse is only for reproduction, not for love. So far in lots of human being countries, men only care about the possessive quantity and quality of women, and women only care about how much interests one man can offer to her. This is just a sale, not love. The nature of this relationship is as same as clients and prostitutes. Unfortunately, I live in this dynasty.

Let's go back to genes, in my theory, the testis and ovary genes are just an ordinary two alleles as same as single eyelids and double eyelids genes on autosomal. Don’t tell me the reason you think someone with single eyelids can only marry someone with double eyelids, is just because they don’t share the same trait on eyelids. Our human, as only one intelligent life on earth, should see the essence of things through outward appearance. Every person has 46 chromosomes; in other words, do not let one chromosome which only occupied the probability of 2.17% covers your heart. Just love someone following your heart.


What is love? Love is simple, to be together. If one day, women can wake up from the daydream of self-deception to find their self-consciousness, nothing is going to prevent two people being together, no matter a man with a woman, or two women, or two men. 

Love is being together.

By the way, I saw some news that female orgasms increase the chance of fertility, and women can have orgasms during child birth. I am almost so mad to hematemesis!!!
