Triple Threat: Gay, Black, Gamer
On being a male gamer who also happens to share the gay gene:
I came out of the closet when I was 16 and a freshman in college. It was approximately several months after I had joined the community college gaming group. I am now 36, and I've undergone plenty of re-inventions since then in my personality as well as my sexuality.
I was fortunate enough in my early gaming experiences with young adults to be able to play characters of alternate sexuality under a GM with whom I shared a short relationship before either of us ridding ourselves of the "bi" label. Playing those characters gave me the strength and the confidence to deal the challenges presented to me by others who were not so enlightened. There were more issues regarding my race than my sexuality, oddly enough, but these too were not all that serious.
To date, since I moved to Atlanta, as a GM I've played two gay NPCs, and as a player, 1 sexually ambiguous character. I have played a variety of ethnicities in my characters, but have never felt comfortable introducing a gay character simply because of the mix of individuals in the gaming groups I've joined in my time down here. I am the only black player in my gaming group as well as the only gay player.
Have I felt constrained in my choices in-game regarding my sexuality? If I understand the question, I haven't actually tested the waters of introducing gay characters in the games in which I've participated. The reasons I haven't vary:
At this time in my life, I don't make sexuality a part of any portrayal of character because the games I play in don't even acknowledge that sexuality exists in the campaign world beyond the "fling for flavor" some earnest role-players engage in with buxom barmaids, so what would be the point?
The guys I play with are all straight as far as I know. I know that one or two of them are "homo-fearful", but usually limit the expressions of that fearfulness to an acceptable level most of the time. Out of a desire to maintain harmony with this group, I don't play the orientation card.
At the risk of starting a flame, I've also noted in most of the games I've played that the GMs for the most part stay away from trying to attach any kind of ethnic credibility to non-player characters of color, and understandably so--if done at all, it's often done badly, and perpetuates stereotypes rather than accurate portrayals. This goes doubly so for gay credibility. The first rule of writing is "write what you know." I think it applies to gamemastering as well. So I don't play gay characters because I don't expect the GMs I play with to be able to treat the existence of the trait comfortably, respectfully, or knowledgeably. I don't fault them for a natural gap in self-identification.
Thankfully, that's not as much a consideration regarding the race issue. I can play a person of color in an RPG when they appear, knowing ahead of time that the extent to which the "black experience" may go in my gaming group will be the safe zone of portrayal of "The Huxtables".
Is credibility of culture a requirement for me as a player to enjoy gaming? I'm one of those actors that prove to be such a nuisance in role-playing campaigns.

I like gaming in character, and anything that contributes to me staying in character and thinking in character is what I gravitate towards, to the consternation of some players and GMs. However, I feel it's my responsibility to cut others slack from my abnormally high standards for an escapist activity, so I concede that certain areas just aren't comfortable or appropriate for what basically amount to civil rights discussions.
Someone mentioned a "coolness" factor in the gay community. Ironic, isn't it? A community which accepts leather-clad role-playing along with sadistic drag queens wearing spandex as if it were a right and not a privilege counts all that as a legitimate subcategory of its culture, but wrinkles its nose when faced the far tamer version we play and calls it "weird".
I deal with this just by being me. To paraphrase Will Smith, "I make gamer geek look good."
Does it get lonely being a gamer who happens to be gay? Sometimes. I know that when I leave a session, and I have plans to go to a club or a movie that may or may not have black-relevant or gay-relative content present, it's like I'm traveling between whole planes of existence. I am making more of a conscious effort to find more friends with whom I can share more than one world, but it tain't easy. And let's not even talk about the romance part.
I hope this long ramble helps.
