That doesn't explain why men have evolved such a strong sense of violent jealousy. And mating with a lot of men actually reduces the chances that she'll be fertilized by good genetics. Women naturally want to mate only with the best, not with everybody around. The moaning is much more likely to be a warning sign to other males in the tribe that she is mating, so that if the one she's doing it with doesn't have the social status and power to keep other males off, they will promptly remove him. It's a turn on for a woman that they can moan without being worried about other men doing anything about it because it means that the one she is doing it with has the required status in the tribe. That's also why women prefer it to last longer, because that way they know that the man is not worried about other men in the tribe removing him, and more time means more chances for that to happen, so it's not only about what the man thinks, but about her testing to see if he will be removed or not. If they were looking for a mixture of sperm from all the men in the tribe, they would prefer a quick in and out procedure. But that's not what women want.
And of course when you introduce civilization, monogamy and family unions; as opposed to primitivism, polygamy and tribal unions, this phenomena is intensified because she's only allowed to mate with her partner and she knows nobody will do anything about it.
This university, like most, has an anti-human agenda, and that's what they're trying to advance with these suggestions. It has little to do with learning truths about human biology, sociology and evolution.
