Despite both couples insisting that in the end the experiment made their marriages better…I have to wonder if a book about it destroying their marriage would sell as well.

Having sex, even with your partner, for the sake of an experiment that serves no realistic or helpful purpose seems to me to just be inviting trouble.

Allowed or not, sometimes I really do have a headache and, unlike congestion, which in my experience sex actually relieves, I think it would only stand to make it worse.

Call me a pessimist, but I think sex is only worth having when you want it…book deal or no book deal.
