advice needed

How do I seduce my doctor? He's a handsome, older, Jewish man with twinkling blue eyes and a filthy mind. My sister went to see him today and jokingly expressed an interest in cheating on her husband and his response was, "Go to a swingers' club." Please note, I do not want to have to make an appointment because that would cost me $150. Yeah, this is a serious fuck you to not having insurance.
