Please no flames... this is a serious question. Recently started training in martial arts (kajukenbo, BJJ, a little judo) and occasionally roll with a friend who also does muay thai. He has been encouraging me to work on my standup game lately (which sucks) and I am resisting it because I am afraid of being punched, especially in the face or the stomach. (Frankly, afraid of being kicked in either place, too.) So far, I have not even put on protective gear like a headguard or shin guards, and therefore there is no standup sparring. I figure, why bother, if that's not the kind of fighting I have any interest in? What I dig about grappling is that you can tap out *before* you are in serious pain (usually) and I don't like pain. However, there is a voice at the back of my head telling me I'm being a chicken and I should push my limits. Any advice out there?
