I'm not in uni yet but my advice for you is not to come out till the second year. That way you have friends that might stick up to you, but generaly people in uni is more open. The snag about coming out in the first year is people might act different around you because you are a gay. I mean I don't want to be the "homophobe" but some people can still be close minded. However there is an argument that your friends might see you as deceptive. To be honest what I can suggest to you is just be in the closet ish. Its not like when you meet a person for the first time, you don't say "Hi my name is [blank], I am gay." I mean stay in the closet as in don't tell anyone straight away, however if they asked you, then you can say it and I am sure they will accept it. I may have baffled here but what I am saying is don't let you being gay affect who you are. People will hang out with you coz of your personality not because of your sexuality. In terms of coming, you can considering delaying it till second year. However, if during your first year some people asked, then its up to you whether you say you're gay or not.
