What exactly is "sex"?

[calpoon]

Sex is fucking, but fucking isn't necessarily sex. capice?

for instance if I say that "I got fucked!" I may have had sex, or I may have been the victim of misfortune.

in my opinion, sex is only intercourse involving a man and a woman, with the male penis entering the womans vagina.

however. it is entirely possible to fuck another person in other ways. ie anal or oral.

but, as i said before, the only real text book sex is vaginal involving a man and a woman, purely because sex is a reproductive act, and that is the only way to reproduce.
