You're a brown belt and you're upset about getting punched in the face? Wtf are you doing? This should be a common occurance and no big deal, definately not worth going to the Internet to post about. I've seen at least a couple of posts about "winning" against other practitioners, I don't see how you can win a sparring match. You win competitions but sparring is all about skill development, you don't beat or win against an opponent and unless there are judges or scorekeepers you can't beat or win, it can be pretty subjective in these situations. if a brown belt is alarmed at getting hit in the face I'd bet he hasn't done enough sparring. You don't beat the less experienced, you play at their level and allow them openings and work on your weaknesses. If you have to try to "beat" a newb you're not that good.
