Tony, I'd think you'd know better by now that I don't assert anything that I haven't thoroughly researched. You really ought to try it some time.
"Among ever-married adults ages 18 to 29, women are slightly more likely than men to be guilty of infidelity (11% vs. 10%). But this gap quickly reverses among those ages 30 to 34 and grows wider in older age groups. Infidelity for both men and women increases during the middle ages. Women in their 60s report the highest rate of infidelity (16%), but the share goes down sharply among women in their 70s and 80s. By comparison, the infidelity rate among men in their 70s is the highest (26%), and it remains high among men ages 80 and older (24%). Thus, the gender gap in cheating peaks among the oldest age group (ages 80+): a difference of 18 percentage points between men and women."
The long and short of it is, although the numbers vary slightly by age group, over all, men cheat only slightly less than women, and the "gap" keeps closing.
Meana discovered that “institutionalization of the relationship, overfamiliarity, and desexualization of roles” in a long-term heterosexual partnership mess with female passion especially—a conclusion that’s consistent with other recent studies.
“Moving In With Your Boyfriend Can Kill Your Sex Drive” was how Newsweek distilled a 2017 study of more than 11,500 British adults aged 16 to 74. It found that for “women only, lack of interest in sex was higher among those in a relationship of over one year in duration,” and that “women living with a partner were more likely to lack interest in sex than those in other relationship categories.”
A 2012 study of 170 men and women aged 18 to 25 who were in relationships of up to nine years similarly found that women’s sexual desire, but not men’s, “was significantly and negatively predicted by relationship duration after controlling for age, relationship satisfaction, and sexual satisfaction.” Two oft-cited German longitudinal studies, published in 2002 and 2006, show female desire dropping dramatically over 90 months, while men’s holds relatively steady. (Tellingly, women who didn’t live with their partners were spared this amusement-park-ride-like drop—perhaps because they were making an end run around overfamiliarity.)
And a Finnish seven-year study of more than 2,100 women, published in 2016, revealed that women’s sexual desire varied depending on relationship status: Those in the same relationship over the study period reported less desire, arousal, and satisfaction. Annika Gunst, one of the study’s co-authors, told me that she and her colleagues initially suspected this might be related to having kids. But when the researchers controlled for that variable, it turned out to have no impact.
Many women want monogamy. It’s a cozy arrangement, and one our culture endorses, to put it mildly. But wanting monogamy isn’t the same as feeling desire in a long-term monogamous partnership. The psychiatrist and sexual-health practitioner Elisabeth Gordon told me that in her clinical experience, as in the data, women disproportionately present with lower sexual desire than their male partners of a year or more, and in the longer term as well. “The complaint has historically been attributed to a lower baseline libido for women, but that explanation conveniently ignores that women regularly start relationships equally as excited for sex.” Women in long-term, committed heterosexual partnerships might think they’ve “gone off” sex — but it’s more that they’ve gone off the same sex with the same person over and over.
I'm only combative with people who are condescending and rude.
