From about ages 12-17 I was approached by 6 girls (full disclosure: 3 online, 3 at school). I am 20 now, and in those three years since 17 I discovered, to my dismay, that I was experiencing a string of anomalies.
It seems that the general culture dissuades females from approaching males. Now, for a complicated reason (basically, I don't get crushes) I've never had the volition to approach any particular girl. I just feel that it would be disingenuous to say to any given girl "I'm more attracted to you than I am to the other generally attractive girls that I know about as well around here." The reason that would feel disingenuous is because I would be lying.
So I've only been on dates when I've had something resembling a girlfriend. They were okay, stuff in the park, a museum, etc. Not really "first date" stuff, but I've been told lunch at a cafe is a nice start.
Shame. I'd really like to have a girlfriend, but there's nobody I'm particularly interested in. I could go out and meet people, but I've found that not partaking alcohol makes that somewhat awkward.
