Thanks. That's what I meant, but I certainly should have worded it better. I've updated my comment.
> If we assume that people with homosexual orientation attempting to conform to a heteronormative society would tend to have more trouble maintaining stable relations and thus cycle through relationships more frequently...
So if I understand you correctly, your theory is that closeted lesbians were sleeping with so many men that it inflated the statistics? And now that homosexual women no longer feel constrained by societal norms, a significant number of men are left with nobody to have sex with?
Well, it's an effect which would explain the results. It's not really my theory, which is that it's a complex of different things, including several that the author explicitly dismisses without any significant basis (or by citing a basis which seems incorrect.) The homosexuality one is one of them.
Most of the series of things the author asserts affected both sexes similarly (“obesity, porn, video games, social media, dating apps, and wariness re harassment claims”) seem likely not to have done so similarly (that's seems particularly true of both porn and wariness re: harassment claims.)
No, the article points out thar fewer (proportionately) young men are having sex, while the same proportion of young women are having sex. That's not the same as the less often / same rate description you give.
> I wonder if dating apps (Tinder, Bumble, etc.) are leading women to have sex with a smaller cohort of desirable men.
Social acceptance of homosexuality has increased, and every study I've seen shows that it's higher among women than men (and I think also higher for homosexual behavior by women than by men). Why do you assume that women must be only having sex with men?
If we assume that people with homosexual orientation attempting to conform to a heteronormative society would tend to have more trouble maintaining stable relations and thus cycle through relationships more frequently (which I think is plausible though not necessarily true), then a greater reduction in the number of members of one sex trying to conform that way would result in the kind of unbalanced drop seen in these statistics.
