At first I was all like



But then I was like

I thought men lose interest because orgasm releases chemicals which makes one sleepy. Of course, the sleepy thing could be self preservation. If ancient woman had partner after partner until she came, one of the former partners might want to bash someone's head in except for being half asleep.

Honestly though while sex is weird, love is even stranger. How else do you explain when a beautiful girl dates/marries a frog?

Well right, men do release a chemical that makes them sleepy and to lose interest in sex, so then the question, why did women evolve to take so much longer than men to orgasm? If men take X amount of time, why do women take X+ 4 (or whatever, I'm not using real numbers here) if there is any evolutionary advantage to women even having an orgasm?

Women having sex with multiple partners is one possible explanation for that.

Romantic love as we understand it is also a modern construct, particularly as it comes to marriage and reproduction, but I guess that's another thread.

And zoophilia is an entirely different ball of wax.

But we know with actual science that sex releases bonding chemicals, so how does that apply?

Sex is also a social activity for humans (rather than strictly reproductive). It doesn't serve a singular purpose.

Bonding with multiple people in your social unit would be adaptive.

I'd just like to throw out there that this doesn't necessarily apply in all cases. I'm currently aware of a situation where the woman achieves orgasm very quickly. And repeatedly.

I'm talking averages, I'm well aware that some women orgasm very quickly and some men take quite a long time.

But this also doesn't take into account the thousands of years of female sexual repression.

Because if the female orgasm's resulting contractions increases the uptake of sperm, wouldn't it make more evolutionary sense for a female to be quickly and multi-orgasmic?

That's my go to excuse if a woman fails to orgasm. "It's not my fault you didn't cum, it's thousands of years of female sexual repression! DAMN YOU PATRIARCHY."

Im going to text every single one of these chicks and have them take it all back, seems like it was their problem all along lol.

Long time for orgasm could also very well have to do with the stamina of the man (weak or strong man stuff).

Perhaps a man who was willing to have longer, more involved sex was also expected to be a better father to his offspring.

lol, I mean it's a few different things - throughout history research into sexuality has had a male point of view, if for no other reason than the most widely known and well established researchers were men. For example, Kinsey didn't fully understand the clitoris. He thought it was an immature sex organ.

Then there's the evidence that women's ability to orgasm develops over time. If you couple that with the societal pressure (at least in America) that women be chaste - well, you get women who are less likely to be orgasmic because they have less experience.

Then there's also evidence that space between the clitoris and vaginal opening influences ability to orgasm. A woman with a shorter span will have an easier time with orgasm, presumably because there will be increased external clitoral stimulation. Which, if we're still speaking in theoretical evo terms - if a woman's orgasm increases the chances of sperm meeting egg, then it makes sense for a woman to be more easily orgasmic. If shortened space between clitoris and vagina increases orgasm, then women would have evolved shorter and shorter spaces, right?

Then again, we live in a society where a lot of men and women think women pee out of their vaginas.

You're right, that would make sense. Unless maybe there's some adaptdation as yet unknown about prolonged intercourse or multiple partners.

Some women also become overly sensitive after too much sexual stimulation - maybe different partners allowed for a break.

I find the topic in general fascinating but given uncertainty about social evolution and the confounding factors of different societal pressures over time it's impossible to be certain about why certain traits developed. We have theories but I don't think I've yet seen one that satisfactorily explains everything, quite possibly largely in part because our species today lives in social and cultural systems unknown when the traits developed.

Who knows how things will look 100, 500, 1000 years or more down the line.

If you're at all interested in the specifc theory I cited here, the book I mentioned is called "Sex at Dawn."

I think the author of sex at dawn also has a ted talk.

You might find this article interesting.

I mean the introduction has a monkey in a bikini, I think it's safe to say I'll enjoy the article.

And yes I do think the authors (there were two) had a Ted Talk.

SGT RJ, are there other mammals that have a mating culture that's similar to the one you described from the book?

Bonobos are weirder than anyone this side of a German sex dungeon.

Dolphins also have a lot of non-reproductive sex, and I believe they do have group sex with many males and one female, usually characterized as gang rape.

Lions will often have two males (usually brothers) as alphas in a pride.

Cats in heat will do it with all the intact males in the area and can have different baby daddies for kittens in the same litter. (I imagine this is true for many mammals where the females go into heat and have large litters)

Cats having sex is pretty aggressive, but have you have seen ducks go at it? Not uncommon to see two or three males gang up on the female, climbing on top of her, pushing her under water and biting her. And if there are multiple males in on the scene they quickly take turns... rinse and repeat.

Very rarely women can have twins with different fathers.

Duck reproduction is really strange in general:

I guess female duck bodies do have a way of shutting down "legitimate" rape.

Fwiw, I think human mating has some similarities to Bonobos and is much more egalitarian than most primates, but is more related to consortship in Chimpanzees. Sometimes when a female is in estrus, she and a male, usually not the alpha, will leave the troop for days or weeks and mate a lot. I think the evolution of romantic love developed more along those lines than as a modern construct.

In general, perhaps always imo, modern constructs don't take unless they are well matched with innate behaviors.

So we've gone from Sex Ed to Sex Ted.

This would explain why sex drops off once a man becomes a father. If he still needed to have longer, more involved sex, he couldn't be a very good father.

pe,

I've been involved in facilitating a few kidney related transactions. "Time to sell" is not a factor - the sale is finalized and majority of funds transferred prior to the donor providing the organ.
