Married men, why not. I think i can say a majority of them were. Many wore rings that indicated they were. Others told me right off, i liked that. Many women i've known who were cheating preferred a married man. A secret is better kept if both of you want it so. My adventures with them were always in a party or private setting. I would never knowing display sexual interest in public where it could get back to a spouse or baby. One advantage they hardly ever try to get you to leave your man. Single guys tried that move more than once.
