Ok, Guy:
I am a ballet dancer, and I am used to the dance belts scene. Any capezio dance belt is ok, you have to worry about the waist, not the size of your penis, if you are gonna be uncomfortable, it is gonna be because of a really thight dance belt almost cutting you in half from teh waist. And the Point of a Dance belt is to give maximum control,specially if -as you said- are not that little. And one more comment: if you are in dance class, why would you get a hard on?? Concentrate, dance is about disipline my boy!
Hope this is helpful ;) [/i]
