I was 13, when I had sex with a girl for the first time - my bff, Ellen. I was 18 and a freshman in college, when I first had sex with a man. It was with a boyfriend of 3 months and I thought that I was in love with him. We did 'it' and it wasn't at all what I expected. Actually, it hurt somewhat and he was apologetic. It left me with feelings of uncertainty. Later, though, with another boyfriend, it was all good but still not quite what I hoped for. It took another 2 years for me to truly enjoy sex with a man.
