i used to be the same i would want a relationship with a girl but i was just aroused by guys!
listen mate dont be thinking about all this and trying to put a label on yourself, cause that just makes u think alot and gets you all stressed and stress gives you wrinkles which are bad!
but seriously dude just go with the flow and do what you want. if you want a guy get a guy, do not try and do something that you dont want, like try and force yourself to be with a girl if you dont want. just be yourself and do wat ever you want with who ever you want! its your life and you only live it once, might as well live it happy!
