Evolutionary speaking, premature ejaculation may not be such a bad thing after all.
So given these basic biological facts, and assuming that ejaculation is not so premature that it occurs prior to intromission and sperm cells find themselves awkwardly outside of a woman’s reproductive tract flopping about like fish out of water, what, exactly, is so “premature” about premature ejaculation? In fact, all else being equal, in the ancestral past, wouldn’t there likely have been some reproductive advantages to ejaculating as quickly as possible during intravaginal intercourse-such as, oh, I don’t know, inseminating as many females as possible in as short a time frame as possible? or allowing our ancestors to focus on other adaptive behaviors aside from sex? or perhaps, under surreptitious mating conditions, doing the deed quickly and expeditiously without causing a big scene?
Still, for recreational sex, it blows. (As it were.)
