I knew about the single beds because that is where we very often had (looking back with hindsight) very unexciting sex.
I also thought at the time he was probably getting his marital exercises at home. I was proved wrong when I met his wife's girlfriend.

Apparently she had denied her lesbian tendencies to have a family. The wife and her girlfriend have had a wonderfully close relationship for the best part of twenty years. Now that her parents are dead she is considering 'blowing her cover' and living her own life at last. I hope she does. Meanwhile 'he' is old and bitter and lonely, accorsding to his family.

I can understand any person, male or female who is denied a sexual/loving life at home looking elsewhere. The problem arises when they bring their resentments to the illicit relationship.

But at 19 none of that really registered. Now twenty years later,happily married to a fantastic guy, with a healthy sex drive and our four kids to love, I feel pity for the errant husband, because he has never found what he craved.
