I am what I believe is called a cisgendered woman; born as and generally present as female. But I have always been attracted to people of both sexes, and have never liked traditionally feminine garb; I almost never wear makeup or jewelry, and rarely wear dresses, skirts, or high heels. I've often thought it would be great to have a male body if I could do so temporarily and non-surgically. Ursula K. Le Guin's The Left Hand of Darkness comes close to my ideal in that regard. But that's fantasy..
I also strongly dislike single-gender events. Granted, I've never been to a men-only event, but the few women-only functions I've attended I've found distasteful. As an adult I've always had more male friends than female, but really I suppose I just prefer the company of people who don't feel compelled to conform to society norms.
P.S. Apologies if I'm misusing the terms "sex" and "gender". Feel free to (politely) correct me if so.
P.P.S. It should go without saying that I am a very strong supporter of same-sex marriage.
P.P.P.S. Google+ invites are being turned on and off at seemingly random intervals, so I can't promise to get one to anyone; it's a waiting game at this point.
