Nearly all women refused to have sex with a man during their menstrual period. That is right. Because if do that, women are susceptible to gynecological diseases, but it doesn’t mean women can’t orgasm during menstrual period.
In fact, women can get orgasm as easy as usual-groan, shudder of climax, and small amount of mucus like egg white without blood from vaginal, some hormones released by brain lead to a refractory period after orgasm. The only consequence is that you must be bleeding during ovulation for 4 or 5 days, but the exact cause of bleeding during ovulation is not clear in medicine. I think unlocking the secrets of female orgasm is the key to unlocking the cause of bleeding ovulation.
Menstrual period just can stop women providing their vaginal to men as a receptacle, but never stop women getting orgasm.
