There must be several other threads discussing the same issue.
Your gonna get hit in a fight or sparring match. Learn to take a hit and Deal with it or you can be like Hendrik and cut your own testicles off in search of mystical power and research old chinese fictional kung fu kids novels for new fighting ideas.
If you dont want to get hit, then dont fight and practise the art of running instead.
Just because you get hit, doesnt mean the technique is bad.
