Do not buy a jockstrap! A jockstrap is not designed for a male dancer, it's designed for a male football or baseball player. Buy a dance belt (thong back)!!! Yes, it is supposed to be tight. When you wear one, you shouldn't feel constricted, but you should have a good snug fit around your ass crack, balls, and penis. You do not want your penis (when it is soft and erect) to flop and move around inside. That would be bad because if you danced while that was happening, it would be very uncomfortable, and everyone would probably notice that your penis had moved. That equals embarassment. Take my word for it. I wish you luck!
