I can understand the desire to loose your virginity. I'm not going to go into details, but I lost mine pretty young, but pretty late in comparison to a lot of my friends. I can remember feeling like I was missing out, because we were early teens and it was made out to be this huge important thing and I was so curious.
I lost it, but it wasn't the experience I had hoped it would be. I think I was pretty weird for a young lad compared to my friends at least, I always wanted my first time to be special. Where on the surface at least all my friends just viewed it as something to brag about and something to get as much as possible. Maybe that was all young male bravado.. but a lot of them did use girls just for sex.
Anyway I don't regret loosing it when and how I did, it happened and I cant change it, but it wasn't the experience I would of liked it to of been, it wasn't anything special or one of those memories you look back and smile at. Also it wasn't even that great full stop.
Basically I agree with Mr Falkor above me ^.^ You don't have to wait till you meet the person your going to marry, but I would advise against having sex purely for the sake of having sex, and wait till you find someone you have some sort of bond or connection with.
