The true answer is that scientifically the penis is made to enter the vagina.. women produce feminine estrogen, men produce manly testosterone.... Scientifically they are meant to go together that's why it is the norm lol.. Im bi tho.. so I clearly don't follow the norm and support anyone who is different than the norm :)

Estrogens (as in plural) [Estrone, Estradiol, Estriol] are not exclusive to women, nor is testosterone exclusive to men. For example, estradiol is actually made from testosteron by enzyme estrogen synthetase. Sperm actually has quite high levels of estrogens etc.

What I'm trying to say is that all hormons are present in both sexes. Women have excess of estrognes, while men have excess of testosteron, but to say that one or other are exclusive to either sex is wrong. 

lol ur really overlooking into things of course women have a tiny bit of testosterone and men have a little bit of estrogen.... lol but ur looking too far into it lol.. thats missing the point.
