if you want to go out with guys you do it. i would be of the opinion that people dont turn bi or gay or str8 its already in them. like if you are gay then there is nothing u can really do about it. same as being str8 and being bi.
just do what you want to, if you want to go out with guys then do it. forget all about the labels, of being gay or watever just enjoy yourself cause your life wont be any fun if you dont do wat u want. i know its hard though but its so much better in the long run.
