Am I a biual individual?

Well, let me start off by saying I've lived with a straight mom, dad, and two sisters. Once in a while, I was able to see my half brother. I was the only guy in the house because my dad was always working. Anyway, as an adolescent I would hear many kids at the schools I would attend make fun of someone by calling them "gay". I have never really acted ly, however, it doesn't come naturally to me to talk to girls; only guys. I would much rather talk to a guy I have a lot in common with than a girl who society considers "hot". Believe me, I would never p up the chance to have with a girl I have a lot in common with (in the future of course). It truly pisses me off when normal straight girls insult ual oriented guys. I haven't had a lot in common with chicks from around here, so I try to form emotional bonds with guys, but they p them up.. it just happens.. I'm 15 years old. The guys around here always talk to chicks in the hallway at school, instead I am talking to a guy I have an emotional bond with at school in the morning to talk about the same music we like and the way society treats people who choose differently than some people. This girl asked me why I always talk to him.. I felt deeply saddened.. I didn't respond.. Especially she said in a rude way she thinks it is "gay".
