We've always been very comfortable in our relationship (married for 13 years). Recently I've got back into shape and lost a lot of weight. DH is the opposite of jealous. If I flirt with our male friends - he either laughs it off, or occasionally even encourages me. He seemed delighted that he caught our 17 year old male babysitter "checking me out" as we left to go out at the weekend. Should I be flattered or concerned?
PS Definitely do NOT intend for my mild flirtatiousness to lead anywhere.
