Damn man, I didn't kiss a girl until after I graduated high school, and I didn't worry about it at all. I didn't have sex until I was 19, even though I can see how people could go way, way past that and still be a virgin. If my girlfriend hadn't came along in my life, I'd probably go through college a virgin as well.
There's not a damn thing wrong with not having sex yet. You're going to college, so you'll probably find someone you like there.
High School is bullshit. Everyone always brags about how they got laid this and that last night and how they made out with this and that. It's all bullshit. There aren't as many people as you think in high school that aren't virgins anymore. Damn, you don't even turn 18 until your senior year! There is simply nothing wrong with leaving high school without kissing or having sex yet. If you worry about it, it's simply because of what other people have told you (or those jackass teen movies), which is mainly bullshit. In college, no one gives a damn who's had sex and who hasn't. Get used to it.
