I was 18. I tell ya, sex is great but it's a skill that comes with experience. You need time to feel comfortable with the person with your clothes off, to become used to the proximity... Sex is like nothing else, it's a total overload for all your senses. So, take it slow, it can be overwhelming at first and even turn into a negative experience if you jump into it before you're comfortable. And it's easy to say you're comfortable when you're alone, or just watching porn (totally unrealistic btw, lol) but it's hard to imagine sex when you haven't done it.
OK, that was a very serious post indeed. I think this is needed:
LMAO AT ALL THE NG VIRGEENS!
*cough*
Oh yeah, and remember that crappy trick people used to play in primary school?
Kid A: "hey, are you a VIRGIN?"
Kid B: "No way dude, is that like a dog turd or something?"
Entire school: "HAHAHA! HE'S NOT A VIRGIN! LOLZ!"
Dumb kids.
