Hmm... I myself am 29 and a half and have never dated. I have found two girlfriends, though, over the Internet; the first I met as late as in 2008. They both ended up being unfaithful to me. I just feel glad that it ended so early - had either been unfaithful later on, when we would've been together, or not told what they had done before far later, when it'd be too late to stop where the relationship would lead, I honestly would've killed whoever of them it would've been. Due to this, I have never done anything intimate with anyone, ever, including kissing. The first girl I am with and do anything sexual with has to be the right girl... my true love. It's of some concern that I'm starting to get a little old by now, but of course the girl I'd be interested in wouldn't mind, anyway - rather the contrary. And I'm aging really well, anyway. :B
Despite living my life alone, year after year, I actually look extremely good. I just am not compatible with people... -_- girls tend to flirt with me, quite often, but although I enjoy it, I, by default, regardless of how pretty they are, think that they aren't compatible with me, anyway... it's difficult to think any other way when you are as weird as me, and never have fitted in, anywhere. While confidence isn't a problem for me, it's difficult to keep up the spirit, often, but what else is there to do than trying to remain optimistic... certainly could be far worse, and in many ways, I see myself as very lucky.
EDIT: -_-; ...this is the adolescence forum. My apologies. Of course, not that my post doesn't hold relevance to how people may feel around that age, anyway...
