Bullshit. Do you think a squirrel performs an elaborate ritual to convince his potential mate that it's okay for him to stick his dick in her? No, he just runs up to her from behind and fucks her. For prehistoric man, as with the vast majority of the animal kingdom, all sex is "rape". This is one of several reasons women are physically weaker than men, they had to be, evolutionarily, for men to be able to consistently overpower women to fuck them.

Like >>1687722, I find it almost mystifying that women receive any pleasure at all from sex. The female orgasm is an evolutionary accident; remnants of what could have been a penis and testes if a fetus became male instead of female, retain their sensitivity in adulthood. Female sexual pleasure isn't even an evolutionary afterthought, it's complete happenstance.

There are alternative hypotheses, for example the idea that female orgasm "sucks up" deposited semen, increasing the odds of conception, but this seems to me to be extremely far-fetched, for multiple reasons but perhaps first and foremost, why would female orgasm be so extraordinarily difficult to achieve. The clitoris is nigh stimulated at all in normal intercourse, and compared with it, the inside of the vagina is practically void of sensation. If orgasm in females evolved to improve the odds of conception, then males also WOULD have evolved larger, thicker penises, as the OP mentions. The clitoris, especially its vestibular bulbs, can be stimulated by stretching open the vagina and pushing with some force against the interior walls on either side, but it, in honesty, takes a larger-than-average penis for this stretching and pressure to be enough to lead to orgasm in a typical mature female.

doesn't bigger penis also mean increased chance for fertilization?

here are some ideas:

clothing - women can't see a man's penis before they fuck

love - rarely occurs naturally but when it does size doesn't matter

vanity - women are vain which means they are most often attracted to themselves, men with estrogen look feminine and in turn have small penises

[Anonymous No.1687826]

>>1687774
Well since a woman can only conceive once every 9 or 10 months, having sex "more often" seems not all that important evolutionarily.

On the contrary, rather than earning the trust of a single woman and "settling down" with her and earning the right to fuck her whenever, it makes much more evolutionary sense for males to go from woman to woman, fucking and impregnating them. In 9 months time you could produce 100 children, versus one or two.

Women can achieve orgasm without penetration (clitoral). Besides, if women enjoy it they are more likely to want it. Back in the day when contraception didn't exist this increased the population.

That depends. If males beating the shit out of each other or otherwise competing for the right between them to fuck the completely passive female counts as a "mating ritual", then yes. If a male convincing a female it's "okay" to stick his dick in her is what you mean, then this is comparatively uncommon, but for what it's worth, does occur in more birds and mammals than other animal groups.

No, actually, the female orgasm serves several purposes.

One is to stengthen the pair-bond between the male and female.
Another is to keep her horizontal after being inseminated (hence why humans usually copulate horizontally). The human vaginal tract is almost vertical; if she stands up alot of the semen will be lost. [Morris, 1968]

>Any possible feature -- or lack of feature -- can be force-fit into the natural selection hypothesis for why features evolve.
That's because any possible feature that exists today is a result of natural selection, therefore any feature that exists is necessarily explainable by natural selection.
We don't ask "why do humans always die before being able to reproduce?", because if they would, they wouldn't exits, and then the feature wouldn't exist.

Rape makes no sense, evolutionarily. Just because you inseminate a female doesn't mean she'll have the child. Remember, females are basically helpless for the last few months of their pregnancy, and children with two parents have a much greater rate of survival than those with one. The most sense for males is to mate for life, ensuring that 100% of your offspring survive to reproductive age.

I wasn't aware human evolution could be discussed as a lump argument spanning millenia, without any reference to chronology.

-Did the most prehistoric tribes of men (talking fucking cavemen) rape their partners? Probably, they didn't know better.
-Did other males (perhaps less physically strong, yet more mentally capable) still have sex and produce offspring? Yes
-Is it possible that those males (who were less likely to be able to establish a "harem" situation) have a tendency to stay with that same, mated female? Yes
-Is it more likely that this mated pair's offspring would survive than the male who left his defenseless partner burdened with child without protection? Yes
-Is it possible that, over time, the development of consenting, long-term relationships would become the norm? Yes
-Has society continued to evolve along these same principles ever since? Yes
-Do we see evidence of the same process occurring in the animal kingdom today? Yes

Is it really that hard? No

[Anonymous No.1688061]

>>1688036

Is it possible that the "homely male" strategy of survival developed prior to the appeance of Homo sapiens sapiens? Definitely.

Mammal babies are not insect or fish babies. They cannot survive on their own or under the care of a single parent.

An insect can lay millions of eggs in 1 go, so a "fuck and forget" strategy works best for them. An ape can give birth to 1 or 2 babies at a time, so having both parents staying together and caring for their child works best for apes.

Considering we evolved from apes, I would say that the "homely male" strategy was developed long before the first "cave man" came to be.

Makes no difference if the women has 'optimal pleasure' or not.

women want sex - desire to reproduce

they only get to reproduce max 1 time every 9 months (if they not slacker) so no time for fuckups.

men can get with a different gal every day, 365 days a year if he horny and got the gals, so it don't matter about genes he always got another chance

so bitch wants to reproduce, but only wants to do it with a genebro.

[Anonymous No.1688118]

Interesting fact: At some point we evolved in such a way that our heads grew massive. This meant women had to give birth to us prematurely so they could fit our huge heads out of their vaginas, and hence we were defenceless as babies. This marked the point in time where males switched from having a huge harem of women, to having maybe 2 or 3 mates- presumably as it made more evolutionary sense to help look after the defenceless young.

Also, human females are the only animal that are NOT fertile while on their period. This is so that males had no way of telling when the women were fertile, so had to stay with them constantly to ensure fertilisation. This could also explain why womens periods sync up when they live together.

Modern times are unique compared to the rest of human history, as men tend to want to have larger penises. In most of human history, such is the ancient Romans, Greeks, and Egyptians, depicting someone with a large penis was a way of mocking them or making them look ridiculous.

If we were to extrapolate to prehistoric societies, we should take the attitudes of these earlier historical societies, rather than our own, as the pattern. If applied to earlier cultures where clothing was less likely to conceal the penis, men with smaller penises would be more likely to gain higher respect and social standing, and so would be more likely to become leaders of clans or tribes.

We can also extrapolate both from human history and from other primates that the leaders of clans and tribes will tend to by far have the most offspring, and leader-selection in humans will as a result tend to be the most driving force in human evolution.
