Weird - i've generally noted it to be the Mums who get more worried about it these days o.0

It's pretty stupid for parents to get annoyed because a lot of sexuality is down to upbringing and how you're made to perceive gender roles :S Anyway, there's not really much you can do unless he does do something, unless you plan on having a heart to heart of course. Personally I can't see it happening if his dad at least pretends he's okay with it, I'd imagine if he hated it so much he wouldn't bother pretending otherwise.
Blah urm I don't know what advise to give really as both of my parents seemed to be fine with it and they're pretty chilled out about most things I get up to etc, it should be okay, the dad just needs to realise that he's still the same person and like he doesn't choose to be gay. If he's pretending to be okay with it then it'll probably be fine. When my cousin came out to his mum she needed counselling and everything lol! But she is fine with it now and I guess people just learn to accept it.
EDIT: Not going to say that!, just go with it, really everything in life has a purpose.
O.o Actually almost every bit of evidence scientific and anecdotal says sexuality is genetic and nothing to do with upbringing? Perception of gender rolls is totally irrelevant?It's pretty stupid for parents to get annoyed because a lot of sexuality is down to upbringing and how you're made to perceive gender roles :S Anyway, there's not really much you can do unless he does do something, unless you plan on having a heart to heart of course.
