I don't know how to comment on this except to say be careful.  And maybe use more padding to protect your, well... padding, if that is the case.  From experience, those little buggers hurt and that is part of the fun and (I think) helpful if you're doing some training in tactics.  You don't exactly want to have baseball sized bruises all over your body.  That said, this was a little more ouch than normal.
