Are there any studies on hormonal responses in gay bottoms to sexual stimuli?
What causes that lip-biting feeling that makes you want to arch your back and be made into a bitch?
It can't be part of the standard masculine toolset.
But male rats given estrogen demonstrate back-arching and female sexual behaviour. Is it estrogen at work in bottoms, or something else?

Why is taking cock "female sexual behavior"? I'm a masculine bottom and I can tell you that plenty of us exist. The man/woman role dichotomy is so much bullshit.

Op, if someone's fucking your ass, why would you not instinctively and reflexively push your prostate into whatever's fucking you.
Are you retarded?

Well put. It is purely physical and has nothig to do with females, they don't even have prostates, they arch their backs for the sake of their clitoris.
