I don't think it will be an issue. Many straight people assume that gay dudes only think about having sex with every single man around them and have zero self control. That isn't the case at all. When you see a hot girl, do you rape her on the spot? No, because you aren't a deviant, and neither are most gays and lesbians. They respect others' preferences, as others should respect theirs.
If an issue arises, deal with the specific issue. I feel that there is no reason for a major policy overhaul for something that I don't think will be a problem.
