Everyone forgot what spandral meant! Like me! Did I seriously hear a woman's orgasm was compared to men's nipples? Wth! Us women need to stand up for equal pay AND take charge, their partner doesn't go off until we do, there I solved the dilemma of our gender roles. This lecture was ridiculous and I couldn't pay attention after the excerpts I just said!! Wish so badly I was in classes to contribute lol

Yes, but why do perverted humans have sex with corpses, animals and poop???

Yeah; doesn't the uterus drop down toward the vagina during orgasm muscle contractions? I thought it made it easier for more sperm to reach their destination. Either way, I'm not looking a gift horse in the mouth.
Sapolsky is my spirit animal! Love each and every of his lectures.

Before I watch this video and most likely realize how far off from the topic this lecture, like so many others, becomes I will state my opinion.  We humans have an interesting brain (and body, but that is irrelevant at the moment) that allows for fairly significant changes to be made as our environment changes.  We can absolutely be programmed through external sources to derive sexual ARROUSAL from things outside of what is in our best biological interest.  Monogamy allows for a human to experience emotions and live a life that best suits our GENETIC needs, even today.  Epigenetically we've seen fluctuations in sexual behavior among societies since the beginning of time, this is due in large part to perceptions straying from interest.  I am not suggesting that there aren't biological mechanisms that at play that cause homosexuality or one to be loose sexually.  Of course that argument can be made, especially if the research is by a Jew!  For brevity I will mention 2 sexual groups.  Normal and abnormal.  The vast majority of the abnormal will be able to trace their deviation to a falling off from normality via media or social rejection / struggles.  Genetically we are better off being born into a compassionate family regardless of sexuality.  Entering into adulthood it is important to focus more on the emotions then the actions themselves when first experiencing sexual activities.  Animals are not subjected to the neural re-wiring that we are due to our comparatively large frontal lobe and meta-cognition.  It is that simple.  Animals are governed solely by biological mechanisms where as our reality can change as well as our perceptions / holographic thinking / re-programming of future behavior.  Save yourself an hour and forty minutes of listening to what is most likely some moron who pays good enough attention in school to get through the painstakingly retarded and slow curriculum and just take what I say as true.  I will gladly answer any questions or put myself out there for criticism.

Isn't female refractory period shorter than male refractory period? 39:92
I could see the professor smoking a doobie while reading the Kama Sutra.

egalitarian sex? hahaha yea right in north america a ugly man no matter how good he is will be insulted by every woman he meets. besides that all of this is still interesting, i wonder what sapolsky would say about modern young people, most relationships i see are 1 male with multiply females, plus this one male usually has zero nurture traits, i think we are slowly turning back into apes

It is a great lecture about Human Sexual Behavior.

I like a lot these lectures, but disagree in the saying, that males would recover faster from orgasm. The other way round, because females can have multiple orgasms, sientifically prooved... min 39.40

I will forever be changed by you Sir. I understand now. I know the difference between good patterns and bad. Your taking the time to post such previously off limits knowledge, is so important. I have also studied chaos and deconstruction of Derrida. It was you Sir that taught me first how important education is. Thank you so much.

1:26:20 - all of those biological differences just prove that gender is absolutely not a social construct, like some people want to believe. Funny that those people saying gender is social construct also claim to be pro-trans rights activists, even though trans people are best proof gender (psychological sexual difference) is even more stable than usual physical sex difference, because you can change your body through surgery and hormone therapy, but you cannot that easily change your brain

Wait a minute, what happened to the depression lecture? Or was that part of one with a different title?

I am listening to this at twice the speed and I think it's still too slow regardless pretty good though.

Humans are interesting creatures. I fall more on the asexual side of the spectrum. I really enjoy spending every waking hour working on animation and music. I have crushes here and there, but I'd rather make cartoons than make babies.
Michelle the Human
The stuff about lifetime monogamy/ life pair bonding in humans being about 50 years old is pretty nutty. In the past 50 years pair bonding has taken a nose dive to the determent of society and average human happiness (thanks to the welfare state).

“In the particular realm of female rat sexual behavior,… the standard dogma has been that the female role is a very passive receptive one …[and that’s only true because] if she doesn’t have enough room to run around [bla bla bla ]… if you’re studying an animal in a setting where they can’t speak in their own language.” THAT’S ME UNDER CURRENT SOCIETY RULES. but anyways.... great class... too bad he didnt cover all possible sexual orientations.
This was really fascinating. I've never been to college or University so this was like making up for it, haha. I get to kind of experience it through the internet. Anyway one of the species who specifically only certain individuals mate in is wolves; with wolves only the alpha pair in a pack will mate, but that is usually because the alpha pair is the parents while the other members would be all of the offspring and siblings, rather than a custom, it would be to avoid incest.

Yes Robert is awsome, but is that my sex drive talking??
