I never chose to like girls.. I guess I was born bisexual. I've always like girls ever since I was in second or third grade.

I'm the same way. When my other friends were experimenting with their male next door neighbor, I wanted to be experimenting with them. I actually don't really have a preference either way at all when it comes to who I'm going to be going out with/doing stuff with. That's actually moderatly uncommon among the bi community. Most people at least have a preference one way or another, but you really dont' choose it.
Being gay/bi/tras etc etc is actually developed since birth. It's in imbalence in your DNA structure or something. I don't really remember, but there are studies that prove you can't choose what your true sexuality is. Granted, you could go make out with another girl even if you're not attracted to her at all, but you can't choose who you are actually attracted to.
