Why Men Find It So Hard To Stay Faithful

by Patrick Appel

Christopher Ryan looks for an evolutionary basis for an all too common occurrence:

When researchers decided to look at this issue to develop a Sexual Boredom Scale, they found that for men, sexual boredom was correlated with variety in partners (or lack thereof), while for women, it was more related to variety in activity. In other words, women were more likely to be satisfied by changes in the sexual what, while men (gay or straight) were more likely to respond to a changes in the sexual whom. It's a simple, unavoidable truth almost everyone knows to be true, but few dare to discuss: variety and change are the necessary spice of the sex life of the male of our species.
