Same here. I'm very self conscious about doing Kata in front a a crowd and tend to stiffen up too much (no dirty jokes). In sparring? Now there is where I excel!
I'm very pugnatious. The Mrs. says she loves it when I fight because I mellow out sooooo much...
I performed my high brown kata in front of 200 people, most of whom were much better at it than me. Their presence was not a big deal. My nearly screwing up a couple of times was. Ahem.
