(Not to mention the pleasure )

It's called The Human Animal narrated by Desmond Morris. (GOOD documentary) I think they usually try to play it once a year or so on TLC.
Near the back of the vagina is like a reservoir for sperm. When you orgasm, the muscles contract such that the cervix is dipped into the reservoir of sperm. The act of doing this makes it easier for sperm to make their way to the uterus. This is part of the biological explanation as to why men are supposed to orgasm first.
Not sure which is uterus and which is vagina?
