bih20: I was wondering..how common or rare is this ? Guys...have you had sex with a girl that at the time was considered just a friend ? Girls...have you had sex with guys who at the time were just friends ? and same for the gay/lesbian crowd. Have you had sex with close friends ? Stay friends after ? become more ? ruin the relationship ? I've had girls around that I would call friends, and I find some of them attractive, but I dont know if I would want to do that because of what it might cause afterwards.
