My husband and I have been married for 26 years. A couple of weeks short of the 26 years anniversary, he confessed to me that he has “serviced” a guy he solicited through Craigslist. He said he enjoyed it and even wants to have anal sex with another guy. He is 73 years old and confessed that he always wanted to do this. He wants us to stay together because he loves me but he enjoys sex with other men more than women. He said it’s okay because it’s only sex. He also said that I should see other men as well. I am 50 years old, in great shape and fairly attractive so I don’t understand this. He is the only guy I have been intimate with. My feelings are hurt and my self-esteem is shuttered. Should I leave him?
