First of all, I am also gay, and I am mostly a lyrical dancer, and ballet is my third focus (I am also latin ballroom) but for Ballet we have to wear tights (as opposed to in lyrical to wear fairly flowy stuff) and ...I would have to say I love wearing them, I don't know why really. But seeing other guys in tights is *very* erotic, I am not going to lie. It is almost like seeing them naked, pretty much. So it is understaindable that you have an errection. Now frist I would have to say you must calm down. When you get all excited/nervous you can't...cool down. Now don't go thinking about like you grandmother in leather, but set your mind to somthing at hand, and it shouldn't be your cock. If you jack off after these events your mind will start making a connection and it will become habitual.
If you have more questions just email me: roger.pollock@inbox.com I know I said quite a bit and I don't know if it helpped at all! LOL
