Most Helpful Guy
Maybe you come across as too attractive for the guys to think they have a chance, maybe they don't see you in the exact same way you see yourself (approachable/friendly).
Not too sure. I find that online people tell me I should have girls lined up, and I haven't been approached in years.
Can't be for sure, and there's many possibilities, but that's my take on it.

It took until I was 22 to be asked out on a date (not as a dare or April fool's joke). Everyone moves at their own pace, dating doesn't have a deadline it just happens when it does.
