@joefromchicago,
I agree with Joe. You don't have to make a decision now, especially if you're confused. If you absolutely have only ever been attracted to boys, and have no interest in girls, then that's one thing. If you're confused, though, just wait and see a bit. Don't freak one way or the other. (You don't seem that freaked though, which is good.) Probably no need to tell your parents anything yet.
The other question is what "attracted" means, though. My daughter is 11 also and has a hard time with defining that. She has a lot of good friends who are boys, and her female friends are always asking her if she has a "crush" on this boy or that boy, and it's not always obvious to her. There are boys she likes a lot, and wants to spend time with, and wouldn't mind hugging or whatever -- but is that a crush?
She currently thinks kissing anyone at all is kind of gross.
I think you're probably a bit further along, but the "naked type of gay" might be roughly in the same category -- when you think of naked type of anyone, is that kind of gross too?
