Let's see:
I have gamed with a lot of bisexual, asexual, and homosexual gamers as well as, of course, heterosexual gamers (I have used real first names, doubting that anyone will know them, if you do, then don't out them, but if you know where the first two are, let me know by PM, I haven't heard from them in years):
James, one of the best DMs I had in college, was a homosexual male, theater major, who was five years older than I was. He was in the SCA and a guild leader. He preferred high level first/second edition AD&D games where we were so powerful that we didn't have to have much to do with mechanics. But he was one of the few people I knew who could play a Malkavian without being kooky. He came out in college long before I got there after a relationship that was a mutual breakup with a really cool girl that everyone had a crush on.
Kevin was also in that gaming group and just liked playing AD&D, he was a physics minor and a history major, and James's roomate. Both were a wonderfully catty pair that taught me how to be a better DM and how to be catty myself. He had a few relationships with women, but one day decided to count people on the street to determine if he was more attracted to men than women and he realized he was gay. His parents were deep southern baptists and came to town once a week to take him to dinner and try to make him come back to the light. He just laughed them off and took their food.
Brad was pretty much a militant gay and came into our group and felt that he had something to prove, even though we already had two gay guys in our group. He was a shy person before he came out of the closet and became very extroverted afterwards especially since his parents told him to never come back home. He wasn't a big fan of D&D and preferred White Wolf games, especially Vampire and Werewolf.
Flounder was from Austin and was a gay guy, but no one knew. Not that he hid it, but he didn't fit the stereotypes. He broke the hearts of half the campus when he told people (mostly girls, but not all). He liked playing D&D mainly and didn't really get involved with my White Wolf games.
Mike and William experimented with homosexuality but realized it wasn't for them. Either of them would pretty much play any game put in front of them as long as they could just get into combat.
Aaron and Max are guys I like to say are fashionably bisexual. They would do it if it were available and they were interested, but all I've ever seen them with were women (a lot of them for Aaron and a few with years between them for Max).
Willie was a gay guy who was attacked in school for being gay (but knowing him he egged it on) and was very dependent on his parents. He has a permanent boyfriend now. He preferred World of Darkness games and was a very disruptive player who would go in his own direction and as a Storyteller would push us down routes that a lot of us found distasteful.
Jeff was in my games in graduate school and ran a vampire game. He is acts rich and effete and doesn't really care if people find out as long as he is not outed. He is attractive, but for him women are just accessories. He says he was a real player in high school, but knew he was gay when he realized he didn't have feeling for any of the girls he slept with.
Lisa was an asexual that I for a brief amount of time convinced her to have a relationship with me. She was a horrible, horrible power gamer and would make gamebreaking characters but would reign them in enough to keep the game going. She kept detailed game folders of every character.
Jessie is truly bisexual. She just dates whoever she is interested in. She likes to play any game as long as someone else maths for her. Her favorite games are White Wolf games and Dread.
Lessa is an asexual slowly morphing into a lesbian and she is a very active roleplayer making hyperkinetic characters. She prefers White Wolf games.
Mel, though I've never gamed with him is a gamer playing mostly 1st edition D&D who is a ftm homosexual.
Tracy and Sammi were a pair of mtf transexuals who were gamers. Tracy died quickly of cancer a few years ago. Both played WoW, but Sammi had been a D&D player first and got Tracy into the hobby.
