Most Helpful Guy
If you don't even have a crush yet then that gives me the impression you don't get out and meet people much. The more people you meet the greater your odds of developing a crush will get. It will also increase the number of guys interested in you.

Online dating seems perfect for you. It's okay to not have a crush at all, nothing wrong with it (even if you've never had one).
Or you can put yourself out there by joining organizations that interest you where guys may be. I would suggest Meetup. com. It's a place where people can go do things in their city and make new friends as well as potential mates.
