Sorry but you're a pvssy, find something else. When I work with new guys, if they are not willing to get punched in the face on the first day, I call it off. If they're not willing to punch me in the face on request, I find someone else. It's not worthwhile for either of us to train together.
You don't have to be violent or insane, but you do have to be courageous and respectful of the sport and your opponent. It's not fair for your opponent to have to hold back because you don't want to ruin your pretty face. My face looks like a train wreck, f*ck it, that's the sport I chose.
When I was doing "boxercise" and "sparring drills", it had NO PRACTICAL VALUE in self-defense situations. When I let people punch me in the face barefisted, sparred full-force without headgear and occasionally with only light MMA-style gloves, that's when you become a bad mofo. If I can take unpadded heavyweight punches clean to the jaw, what's your b*tch-ass gonna do?
