Uhmm Gay (Read Details)?

Ok, listen. Im only 13 years old and I think I am gay. I mean its just sometimes I get turned on by guys and not by girls. I have NEVER gotten turned on by a girl. I have heard that sometimes during puberty you go through stages where you can be attracted to the same , but I dont think that for me. I really think im gay. How do I know if I am or not? Ughh, this is so aggravating. How would I tell people? Please help here. Oh, and s, do NOT answer this question. Thanks!
