After being married for 23 years, I wanted sex but not a relationship. This is dicey because you can’t always control emotional attachments when body chemicals mix, but with the married men I guessed that the fact that they had wives, children and mortgages would keep them from going overboard with their affections. And I was right. They didn’t get overly attached, and neither did I. We were safe bets for each other. I was careful about the men I met. I wanted to make sure they had no interest in leaving their wives or otherwise threatening all they had built together.
