I Desperately do not want to be gay ?

Ever sense 6th grade I have been called gay. It has, and continues to fallow me through high school. I've been called this by everyone I know, even people I don't know. It has literally put me through a living hell. Trying to fight it my whole life I felt like I had to act a certain way to be accepted. I get so angry at the people that say it to me, and I don't want to feel this way anymore. I don't understand why these people feel they have been given the right to judge other people on there possible sexuality. Even my close friends that know it bothers me still give little "digs", referencing to me being gay. Even my own family questions it for some reason. I am a fairly social person and I would say most people would say only good things about me. I am a very real person no b.s., And I'm not necessarily girly I just have a lot of girl friends compared to guy friends. I sometimes ask why people think that and when they actually think about it they can't come up with a reason why they think I'm gay. So sorry for this being so long but I need help. I've been questioning lately if I actually am gay or not, but I really hope Im not. I always pictured myself getting married someday and having kids and being gay would just screw everything up. I really want to find myself and except myself for who I really am inside, but it's really hard for me.
