I am married and do not wish to cheat on my husband, nor am I tempted. However, my married co-worker is also a teacher and is mildly attractive but knows it. He always talks about how this girl and that girl used to want him. He also has this weird OCD thing and I know he would probably be missionary and lame in bed. That said, I have an intense desire to sexually frustrate him without actually allowing him to have the satisfaction of even knowing I am even attracted to him. He is in his older 30's. He is a cocky guy who needs to be knocked down a few pegs, but I suck at this type of thing. He also makes fun of everyone else at work, particularly the more unattractive women. Advice please.
