Jamie,
I am taking belly dancing lessons. I am the only male. I dance as a man, but wearing women's clothes, so I am actually taking the class as a crossdresser, but it doesn't bother anyone. Proper men's dance clothes are not that different, but cost more. Here is me with some of the female dancers: http://www.flickr.com/photos/juno_dancer/5744182306
I realized that being a male dancer really gets you accepted into the dance group. They know you are a bit feminine, but are not too concerned over whether you are gay or straight. They only care about your "dance orientation", meaning that you are there for dance and not to look at women, regardless of your sexual orientation. It is wonderful to be accepted as a person and not just be seen as a man. In fact, I think that a lot of male dancers might have been crossdressers if they did not start dancing. For anyone that really wants to quit CDing, becoming a male dancer may be the second best way for a man to express femininity. It may even be good "coming out" therapy for those who are afraid of public expression.
For me, dancing has been incredible. When I was in grade school, the whole class got dance lessons (the disco age). I was a total klutz, and was always the last choice of a dance partner. As I have become more female, my brain function has become more balanced (get that right hemisphere in shape!) and I find myself a rather good dancer.
