Yeah, as someone who is extremely close to aromantic (which is a pain to tell people. "You're a romantic? You don't seem like it.."), and has never been in a relationship, I feel ya. Some things in relationships are plainly obvious even if you haven't ever been in one.
No, it isn't. Glee irritates me, and I'm not a fan of acting, even though I enjoy lots of other performance arts. If you're thinking that it's weird since the stereotype is that gay men love all those things, don't worry about it. Almost every gay man I know is not like that at all.
