Happy wife, happy (sex) life. At least according to research done by psychotherapist and author M. Gary Neuman.
He conducted a study with 400 married women to find out how often happy couples have sex, and subsequently answer the question many couples no doubt ask themselves: "How much sex should we be having?"
Neuman points out the indicator of a happy relationship correlates to how often the couple has sex — not how great the sex is. His findings also indicate that there's a staggering difference between the frequency of sex between unhappily married couples and happily married couples.
In a video by Business Insider, Neuman quantifies his research, explaining that happy women (or couples) have at least three times as much sex a month than unhappy couples.
Check out the exact numbers below.
So where does this 'unhappiness' factor come from? According to Neuman:
Once the two-year period hits for couples, he explains, couples face a cross-roads that when not properly managed contribute to less and less sex.
Luckily, there are ways to fix that.
