Oh gosh, well... I mean, I'm still coming out to people. It's difficult because it's usually just one person at a time, but also it's easy because I can casually mention my girlfriend in convos with people. Cause that's a normal thing to mention, really, so I just "My girlfriend this", "My girlfriend that", and over time people usually either smile a nod and we keep talking, or they suddenly get even more friendly - because I've found that some people have that reaction to meeting gay people. Their face lights up like YAY, and it's always funny to me, because a lot of the people that give that reaction are straight, and I previously thought maybe they wouldn't approve. lol
Out of the people I work around I've had positive responses. Heck, one of them, back when I was still dating my ex (who's a guy), even said "Boyfriend?? I thought you were gay", and I had never mentioned it to her before.
I'm bi, granted, but I call myself gay because I heavily lean towards that.
Before I was with her it was a little more difficult, and there wasn't really a way (or a reason) to flat out tell people unless guys hit on me to the extent where I had to spell it out for them. For some people, I think being gay isn't a huge part of their identity, but it is for mine, because I generally seem more guyish and the way that I speak isn't very feminine. I don't fit the gender stereotypes for a girl. I feel like people find that a little weird, until for some reason they find out I like girls, and they're like "oh, that explains it". lol I also lean towards being trans, and I was out for that with some close friends and my mom, until I sorta steered away from it for a few reasons.
Over all, I'm tons more comfortable telling people now, but it took me right up until the last years to really start coming out. I do envy people who were brave enough to do it in their teens!
