Or casual sex.
Hey, GD.
also known as sexual intercourse. It's usually done in someone's bed when nobody else's around.
I have been reported to be the most mature about the reproductive system, as a student, in my entire school. (about 1000 kids) It's because I learned the entire thing when I was 4 or 5, when I used to use ADAM on my computer, and reading my 1500 page book about human anatomy and physiology at the same time. I was in Orrington back then. Ahh...the turn of the millennium was great.
