I lvoe gay guys, I want a gay best friend.
Anyway, I don't really knoww what I can tell you, I suposse it may be hard but the best thing to do would be to come out to your family, because if you don't then your mother's going to do it for you. & I'm guessing it would mean more to them if you did it yourself. I think you should just suck it up & tell them, I mean if you're mum's okay with it then I can only guess that the rest of your family won't have a problem with it.
Good luck & sorry for the crappy advice.
