Just how long does sex endure? How does sex endure such a long time? I wonder why (especially peoples) sex persists more than just a couple of seconds? My idea is the fact that the shorter a man is taken by it to ejaculate, the smaller may be the danger which he gets interrupted by way of a rival or a predator. Consequently, males whom ejaculate quickly get an evolutionary benefit in the long-lasting. But, as human being intercourse persists a few moments, i am obvioulsy incorrect with my argument. Anyone understands why? 2 Answers 2 There are plenty of pets with brief procreative periods, while you recommend. In chimps, intercourse takes ten to fifteen moments – not as cute asian ladies time than humans. So that the real question is really why have humans developed to be varied? I do not think some of the responses predicated on physical fitness are specially compelling. It is not like sex feels as though operating a marathon or less in good physical shape individuals can’t have the ability to ejaculate inside their lovers so that it appears not likely that the sex that is lengthy serves to tell apart fitter individuals.
