I've just realised that in most nature documentaries I've ever seen, the male animals only get to have sex for a brief period of the year, and even then it is usually only the dominant male. Also, a few thousand years ago (when we were basically anatomically the same as we are now), we wouldn't have had the time to be indulging in regular sex. So, is regular ejaculation (even through intercourse) actually what we are designed for?
Interesting question. Chimps and gorillas fuck year-around like us and wet dreams happen regularly (allegedly, I haven't abstained long enough to check for myself lol) so I'd say regular ejaculation is natural. Not 8 times a day, though.
It isn't just that. There's plenty of things we do that century ago people weren't doing. I've heard it said that if we were to live in the world that the early humans lived in we would die because the environment will kill us. I think just because animals or early humans did something doesn't mean we should do it. It should also be said since prehistoric times porn has existed, it's just that it was very different back since it was produced in the form of rock art and figurines. The truth is there's really nothing new under the sun.
Imagine having to travel for years to find the right cave painting to fap to. Nofap was easier back then.
