Not a single sexual encounter until I was in my mid teens. I think I'm a weirdo. o.O

I remember masturbating like crazy though.

Oh yeah. Doesn't really qualify as "sex', but dated a few girls in high school because I thought it was necessary "cover" for my "sick desires" (Lol) and I ended up in a brief make-out session with one of 'em - I found it extremely gross. ;P
