I have a pull towards girls and I'm one?

Okay I'll just get straight to the point. I think I'm a lesbian. I have had this pull towards girls and I seriously think I am a lesbian because I am not very interested in boys except for emo ones and they usually tend to be gay. I am only twelve years old so I don't know if this is normal.... because I hear everybody eventually goes through a bie curious stage in their life. But I seem to have a 'crush' on a girl and I really feel like I am a lesbian because I like to see girls in bikinis and I like the girl body and I think penises are very gross. I have been feeling this way for some time now and even when I was in kindergarten me and my friend would kiss so I don't think I am just going through a normal stage in my preteen years. So please just tell me what to do and if you think I really am a lesbian or bie. Please don't say mean things like 'get laid' or anything like that. Thanks. (:
