I don't have any gay family members, but I've got several gay friends and coworkers. We hang out, full stop. Sometimes we talk about relationships - oddly, my new boss is a lesbian and her relationship with her partner is very, very similar to my relationship with SFIE (her partner buys her better jewelry, tbh). We frequently commiserate with each other.
Both the departments heads for my units are gay and one is in committed relationship with another colleague. I've hung with them, they are a lot of fun.
Their sexual preferences/orientation isn't an issue. I can't imagine why it would be? We have plenty to talk about without that. It's just a simple fact in their lives, like my relationship with my husband or the fact we've got a dog and 2 cats or that our son is dead. It's not the focus of conversation and they certainly don't act any differently because they are gay.
I'm actually just sort of baffled by this post/question.
