This is rather vulgar considering how I usually post, but I was curious as to what the best 'part' of it is. Naturally, the answer is a matter of opinion, so I'd like to you say what you think the best part of sex is. For all you virgins, a simple hypothesis is fine. If (scarce as you are) some of you aren't virgins, I'd like what you thought it would be before you had sex, and what you thought afterward.
Strange questions, I know... But hey, I'm curious.
