Style question

Whenever I do spins, 5's or 7s or anything, I have this problem with my arm swinging around and sorta ending up in front of my crotch area, instead of beside me. I don't wind up hard at all on small rotations like 3's yet, it still always happens. It doesn't affect my skiing at all, but it just seems like it looks terrible and I hate it. Any idea what the problem would be? Or should I invent this and call it the stank arm.
