My best friend asked me to fuck his wife while he’s in the hospital because she misses sex.

I’m more than willing, but my wife said no. Then he asked if I’d do it and just not tell her. I would, but there’s also my wife to consider. What do you think?

One part of me thinks you and your friend’s wife should get tested and go at in secret, because I firmly believe that humans are not designed to be monogamous — and evolutionary science backs me up.

But while I can argue for non-monogamy using evolutionary biology, it doesn’t really fit into how we live our lives today.

More to the point, though, you have a wife to whom you’ve made a commitment. You chose to lead a life of trust and love with her, and at the end of the day, it’s not your job to satisfy your friend’s wife. You’re not beholden to her.

And while I’m sure it would be fun in the short term, I can’t think of a long-term situation where it doesn’t fuck up your life. Refer your friend and his wife to swinger websites to help them find a more appropriate sexual partner.
