Анален оргазъм

[Fisherman]

why do some people enjoy shoving a stick of meat up their vagina?

Sapolsky answers, that species do not reproduce out of a duty to preserve their kind. They engage in coitus because it feels good.

Answer being: whatever floats your boat.

But the vagina is especially made for shoving sticks of meat,unlike the anus.

The "feel good" part comes from our brain,the brain kinda gives bonuses for serving your purpose.People need to understand that pleasure from sex comes second,reproduction is the solely purpose of sex.
