It is wierd to think about, but the reasoning behind having sex at school was that we were so deathy afraid that our parents would find us. So we did it in a public place, like a park, or at school, like in the catwalks of the auditorium, or the i-tv room, or the dressing room under the stage...
I think back on it now, and think I was too young and EW! Who has sex at their highschool, I mean, come on!

Maybe I had more issues then, so I have less now.
