An interpretation of Maslow's hierarchy of needs, represented as a pyramid with the more basic needs at the bottom (From Wiki).
Apparently from the pyramid, the first level consists of our physiological needs, including breathing, food, water, sex, sleep, homeostasis and excretion in Maslow's theory. They are all the basic requirements for human survival. The point is Maslow believed that sex is also one of physiological needs at the first level, and all physiological needs are the most basic and strongest needs in the hierarchy because if a person is deprived of any of these, the person will die.
There is a paradox here. How do you explain lots of women don’t like sex and they think sex is a chore, if in Maslow theory sex is a really basic physiological need? You can’t give a reasonable explanation for that under current theory of female sex research. Of course you can say that maybe Maslow got wrong, but as a male, I think Maslow really thought sex is a basic physiological need, not only for himself, but also for every male. You also can say maybe sex is a difference between males and females. I wonder to know why this difference happens only in sex not in other physiological needs. I think we can’t put sex on the first level, if there is a real difference between two genders, because the theory of Maslow's hierarchy of needs is proposed for entire human being including females. I think there is a possibility left, Maslow got 100% correct, and the problem really happens on female selves.
Frankly speaking, Maslow was not wrong, sex is a basic physiological need for human being, but women just didn’t figure something out yet. I think one day when the truth is opened to the public, women need a real sex more than having a so-called women’s day.
It is noteworthy that Maslow put the sexual intimacy at the third level, different from sex at the first level. From this point, we can see that Maslow thought love is love, sex is sex, and the two are different from each other.
