That's really bad advice!
Medically speaking, that is. To make it simple... If this guy is so aroused that he can ejaculate during class, in public, it's very likely that his "resolution" period will be short, and he will become aroused again shortly thereafter.
For an individual to focus so much on his arousal during a ballet class while working as hard as he should (working hard on ballet), and on top of it in public, there may (I said "may") be an underlying physical or psychological disorder or both. I'm not saying this guys is "sick," in any "perverted" sense. I'm saying that there is a possibility of an underlying problem that may need some professional attention.
My advice to this guy, "Talk to your family physician."
There is another possibility...this is a clever story. In all my years in ballet, with all the male dancers I've known, with all the male friends I have (including several with sexual addictions, and some with dancewear fetishes), with all the frank discussions we have had, I've never known any guy who had this problem.
So Who's on first?
