A few years ago I felt the same as you in respect to the whole "I want sex right now" idea, yet although I didn't strictly go about it in the way you're thinking of doing so, it by no means happend in the most idealistic of ways, but at the time I really didn't give one and just didnt regard it as a big thing.
Two years on and I feel completely different, I often wish I was still a virgin, not to say the first time was by any means the last, yet I do think that if I was a virgin I would act much differently within the relationships I get into, by all means supress your urges in other ways, but by having a quick shag in a club with a nameless stranger is a stupid waste of your virginity.
Im not saying you should remain a virgin untill marraige as that would be highly hypocritical, just maybe try and crack out of your shell at college and find a boyfriend, or even just someone you are comfortable with and go about it that way?
Just even if you think you know how you feel now, you might not feel the same way in the future and you'll always remember that as your first time, and do you really want that?
