I have found this to be true.
I have been married for a long while.
I am very happy with my wife, and have no interest in leaving her.
It utterly amazes me that women of various ages are sometimes highly attracted.
Very flattering.
Currently, I am being flattered at work by a married woman fourteen years my junior.
If I had known thirty years ago what I know now, college would have been even more entertaining than it was.
OTOH, my wife tells me that she is glad that I didn't, since she found me more attactive as a naif.
