if they think of you differently, that's their problem. think of it this way:
it's who you are. if you're that positive about your sexuality at age fourteen, i don't see anything wrong with having a girlfriend. even if you weren't positive, there shouldn't be a problem because you are who you are, and really, nobody should interfere with that.
i know you're afraid that people are going to think of you differently, and that's a scary thought. the truth is, some people probably will. keep in mind, though, that there isn't much you can do about it other than roll with the punches. i went through the same thing, and know how difficult a process it is to go through. you'll get through it though.
if you ever need to talk to anyone, pm me. i'm all ears.
