When your mate is ovulating?

I just came across a fascinating article - … ml?_r=1&hp - which argues that men in stable relationships tend to suppress their natural urge to chase down ovulating women (outside of their partners) to safeguard their own union. What I found particularly intriguing was the discussion on how a woman’s physiology subtly shifts outwardly when she is fertile—changes like body scent and voice pitch—which are designed to encourage males to mate with her by boosting their testosterone levels. My wife has passed her reproductive years, but I’m curious if any husbands of younger wives can weigh in. Does this phenomenon affect your ability to stay chaste when they’re “in heat”? It must be quite a challenge, surely??
