>What is the evolutionarily advantage for men to have an orgasm button up their butt hole?
>The evolutionary advantage is when the men of the tribe go on a hunt the dominant male still needs a sexual release. Because there are no women around he forces a smaller male to take his cock. If the smallest male in the tribe keeps crying and fighting the dominant males might get angry and just kill him. But if he gets pleasure from being fucked and enjoys it he can become submissive to them and it can help improve his social position in the tribe.
