Having less sex is certainly a bit sad, as without enough experience doing it, most people will never do it properly enough to truly enjoy it. But I don't think that should alarm anyone, this is not the source of the fertility drop, our species does not not a very high sexual activity to trigger reproduction. And by the way, I don't think that any kind of population collapse is on the horizon, we'll certainly experience a population stagnation, maybe a slight to moderate reduction at some point, but what we're about to see is the flatter part of the sigmoid, and this should be considered good news.
