Pain is only a passing interest of mine and, in order for me to enjoy it, I need the right chemistry with the sub. The tougher I consider a sub to be mentally and physically the more I will enjoy seeing them in pain. 31 is a a friend that I sincerely respect both in and out of scene so it may seem counter intuitive that I enjoy seeing him in pain. He is a very tough and motivated individual though.
The clip of him below is one I have enjoyed many times. I love seeing him flex and moan in a tough position while a bit of electro is applied to his balls.
