My advice...go for it! Ballet is a physical experience that many young males need. You learn to center your body, which is so important for any sports.
But I see a problem....you talk about wearing tights and leotards as if there were something magical about dancewear. OK, in some ways it is, but if you're serious about ballet the dancewear becomes work-wear. It's a uniform for this art. It's necessary for your teacher to see how your body moves.
Dancewear is work-wear. That's the simple of it!
