My dance class experience
I think it's great you are doing something you enjoy and keeps you fit not to mention the gracefulness factor. I took a class last summer, not ballet, but burlesque which was really fun. More forgiving than ballet, I don't think I have the skill for that, but a great workout nonetheless.
At first I felt a little akward being the only guy. But by the third week of the eight classes, the girls were very accepting. I think they saw I was there to dance and not to ogle them. About that third week I was wearing heels during class and we were working on a routine that involved removing your bra. Not to worry we had leotards underneath. I didn't go in full girl mode to the classes but everyone was fine as we learned different routines with glove peels, feather boas, stocking peels, and even tassel twirling. It was so much fun.
The final class was a recital for family and friends where I did perform fully en femme. It was very liberating and I'm thinking about doing it again this Fall. For any CD's looking for a fun time while dressed I would highly recommend this option. Just find a group and check with the instructor beforehand.
