Touching yourself during spouses exam

I don’t remember reading any questions about this but if there are, we can just close this down. I always make sure that keys and change are in my right pants pocket so that my left had is free to use to touch my penis during my wife’s exams. Since I am behind the doctor, I’m able to touch myself as soon as he exposes her breast for the exam. Wonderful feeling! Anyone else??

I'm not sure it is appropriate. You are effectively masturbating in public and bringing a non consenting person into your sexual play.
