I don't think it is good to discuss our marriages with others, unless it is a positive comment. It is a really bad habit to get into, nobody is perfect and I know I am not, but I would not tolerate my husband discussing it with others, especially our sex life.
I used to go to work every day with a new complaint, and decided to stop as it is not a productive use of work time, and devalues my husband, and our relationship.
