Haha, noooo, when that friend made that comment, I honestly just thought it was funny, because I've totally done things like that too. Once, I was in a bar and got to talking with this girl I met about her fiancee, and then we started talking about how I'm a writer. She asked me who my favorite author was and I thought and eventually gave a nod to Virginia Woolf. She was really excited and I just said, "Yeah, I feel like she's a very queer author to choose as your favorite ..."
Also once some people I had just met were talking about how their roommates reacted to them being gay. I chimed in with my own stories, and then within three days one of the girls had asked me out. Sooo ... there's that? (That's another option, btw. Just straight-up ask for a girl's number or ask her to get coffee or a drink sometime, haha.)
As far as friends' reactions, personally, I'm at a point in my life where I feel like anyone who isn't okay with it doesn't need to be around me. That has taken me years, though, and I recognize I'm really lucky in that respect because I'm able to be in environments that are mostly accepting. So, yeah, I think being comfortable being "out" is A+.
