I also kind of mentally matured in a weird way. I never had that horny teenager phase, and I've always been way too mature for my age. At holiday dinners, when all the other kids would leave the table to go off and play, I would stay sitting with the adults and just listen to their conversations. In high school, all of my friends were girls. I never had any real male influences (my dad is incredibly tame; I'm not sure I've ever heard him talk about sex my entire life).
It was until my sophomore year of college that I finally started hanging out with other guys on a regular basis. They cursed and farted and talked about lots of inappropriate sexual things, and it took me a lot of time (and a lot of alcohol) to allow myself to get involved in that kind of stuff. I think that kind of male-male bonding is very important. Now I'm 24 and I have an amazing group of guys that are my best friends. When I moved a little over a month ago, it broke my heart, and I spent the first two days very depressed because my friends were no longer living down the street. But I've already gone back and visited twice since then, so I've gotten over that.
The point that I'm making is: I think that male bonding kind of thing needed to happen before I realized I wanted a relationship. I needed to be broken of my old "one of the girls" persona.
I have my group of guy friends. Now I'm finally ready for a girlfriend. And I think knowing that you're ready is a very important first step. I was never really looking before.

I find this very confusing. Rather jaw-dropping gender stereotyping.
Your dad isn't a "real" male influence because he's "tame" and doesn't talk about sex? Real men have to conform to this rather offensive picture of maleness you've conjured up? By the gods, do you really think that men and boys are only capable of talking about sex and drinking beer and laughing at farts? Why do you seem to think male-male bonding means adherence to these somewhat offensive stereotypes?
Furthermore, if you have to alter who you are to fit in, then I doubt these people are really your friends. Friends accept you as you are, not on the basis of your conformity to ridiculous gender stereotypes.
As someone who has always had close friends of both sexes, let me tell you there is no difference between bonding with a male and with a female friend.
