Jennifer (name changed) didn't have sex with her ex-husband on their wedding night. "I chalked it up to fatigue," she says. But should it have been a red flag? Well, maybe.
It's not that it didn't happen that one night that was the problem; it's that it was the first of many sexless married nights. As an engaged couple, Jennifer and her fiancé were doing it about three times a week, but once they said their vows, it quickly dwindled to about once a month — sometimes less.
Some experts call marriages that average 10 rolls in the hay per year or less "sexless," but other experts take the word more literally, like Susan Yager-Berkowitz, who coauthored (with her husband) "Why Men Stop Having Sex: The Phenomenon of Sexless Relationships and What You Can Do About It."
