I've never had massive problems with homophobia at York University. A few ******s in the first year used to run through the corridor shouting faggots because there were three of us, but that's about it.
There isn't much of a scene in York, although many gay people still go to Toffs on a Sunday and there is a pub which has a gay night on a Monday, although I've never been!
I don't really like any 'gay scene' though, so I guess I'm not the best person to ask.
There is an LGBT society, which I don't attend because it is quite a sex driven society and I don't really like that.
I can't really complain though. I came out in York, I had my first relationship here, I've got lots of friends here who are gay and I haven't experienced too much homophobia.
