Honestly you are not the only one. I worried about it and found I was worrying about nothing (it was completely un-spectacular, but lasted a good 2-3 minutes). I know quite a few of my friends have never kissed anyone and honestly they are normal people (and they are about 18). I know its easy to say don't worry about it (people say this and all you do is go 'yeah right') but honestly I wouldn't. You'll probably still worry about it anyway but I will say that when you do kiss someone you will either be a) What was all the fuss about? or b) Wow, can we do that again please!? Don't worry you are certainly, most definately, positively not alone in this matter. That I can say for sure!
