Re: the splits..........OUCH
im guessing not his balls.
im guessing that he strained his groin muscle. it happened to me.
strech your groin every time it hurts and tightens up. have someone help you as well. if you think the pain is unbearable, see your doctor to see if you really pulled your groin. i ended up pulling mine, but your pain might go away after a couple of days.
take my advice though, i had experience with this kind of thing.
by the way, youll be fine
