Only thing i can tell ya is not to try to hard. Just be yourself and if a person likes you then lovely things will hapen.
Just because you say "guys don't do nothing fun no more" doesn't mean you should get a girlfriend.
doesn't mean that you are a lesbian or bisexual! you should be attracted to girls and have some kind of feeling of life being normal with a girl where as it didn't feel right with a guy!
maybe you don't have to find anyone yet? you seem kinda young, but i am just making that assumption because (no offence) but your answer seemed kinda immature.
what i think you should do is, just get on with your life and see what happens. if you meet a guy but you are attracted to him, then great. but if it happens with a girl, then that's okay too.
also if you are wanting to find a girlfriend when you are also a girl just because it is fashionable to be gay, then that isn't right because you are not being fair to yourself. just go on as normal and see what happens.
There is a bar in New York City called "Witches Brew". You might try there if you are old enough to get in.
