NCBI ROFL: Apparently women (but not men) like monkey sex… literally.

By ncbi rofl | January 21, 2011 7:00 pm

A sex difference in features that elicit genital response.

“Previous research suggests that women’s genital arousal is an automatic response to sexual stimuli, whereas men’s genital arousal is dependent upon stimulus features specific to their sexual interests. In this study, we tested the hypothesis that a nonhuman sexual stimulus would elicit a genital response in women but not in men. Eighteen heterosexual women and 18 heterosexual men viewed seven sexual film stimuli, six human films and one nonhuman primate film, while measurements of genital and subjective sexual arousal were recorded. Women showed small increases in genital arousal to the nonhuman stimulus and large increases in genital arousal to both human male and female stimuli. Men did not show any genital arousal to the nonhuman stimulus and demonstrated a category-specific pattern of arousal to the human stimuli that corresponded to their stated sexual orientation. These results suggest that stimulus features necessary to evoke genital arousal are much less specific in women than in men.”

    Now that’s bizarre.

    I gotta stock up on some monkey porn…

  • Richard Steven Hack

    Well, reportedly human females are the only species that can stimulate sexual response or sexual desire in various animal species, supposedly because humans in the prehistoric past had a history of copulating with various animal species, especially human females. Most animal species are allegedly sexually aroused only by sexual signals from their own species. Human females are allegedly an exception to that general rule both in their reaction to other species sex, as this study shows, and in stimulating sexual desire in other species.

    Way to go richard, you expanded the article! 5 points for originality!

  • xeenmeen

    LOL, pretty funny stuff dude.

  • tycenzig

    I’ve known this for years. Anytime I wanna get my lady going for some sexy time I pop in Monkeys Gone Wild. 5 minutes into that it’s monkey time in our bed!

  • Nao

    Wow, women are gross.

  • dwinstone1

    I was under the impression women did not generally respond well to visual sexual activity, but rather responded to more emotional story lined based porn. So what was the monkey porn story line?

  • OtherInformtion

    The reason for this is thought to be the potential for infection due to damage incurred during rape.

    It appears that human females witnessing any kind of intercourse begin to lubricate. This doesn’t actually mean that they are interested or enjoying what they are viewing. It is a physiological response by their bodies in case the sexual activity will involve them in the near future, willingly or unwillingly.

    Not lubricating could lead to tearing and damage in the case of unwilling sex. Tearing in that area can lead to infection.

    • Mark Eccles

      Most males animals have a penis bone, a baculum in their penis to aid penitration. I hope you know humans don’t have one. So I wonder how successful rape (unwilling sex) is as a way to reproduce.

  • CyberShaman

    What’s funnier than the last 3 or 4 comments is that no one challenged Richard’s credentials. It would appear that all he added to the article was bullscat. “… humans in the prehistoric past had a history of copulating with various animal species” = FAIL.

  • Laila Moysey

    I highly recommend reading “Sex at Dawn: The prehistoric origins of modern sexuality”

    @OtherInformation – excellent hypothesis – is it your own? If not, do you have a link?

  • Nick

    Women researchers are often raped by larger “monkey” species when they go native. The orangutan is especially known for this.

  • Nova

    cite! cite!

  • Terry Grinnalds

    Nancy Friday, many years ago, published two books about sexual fantasies, one of men and one of women. There was a whole chapter on women’s fantasies about sex with animals – mainly dogs, and not a single example for women. She commented on this in her book on women’s fantasies “The Secret Garden” I think it was, saying the difference was real. It just was not a fantasy for men, but was prevalent with women.

  • Crossfit Equipment

    Man, those are some evil looking monkeys!

  • Mark

    You have some strange associations when it comes to the concept of sex.

  • Sanford Hall

    Hi guys,

    let’s keep it real and be mature about it. So keep it clean while keeping your head on your shoulders straight. You can still be funny while telling a clean joke in the way Tycenzig put it.

  • Jim

    Anyone seen a monkey with a brazillian? Bet that would skew the test results

  • virtualmel

    This makes sense to me as women are, indeed, sexually excited by extra-sensory stimuli… perhaps that explains how a beautiful woman is not always matched up to an Adonis-type male. The intuitive and creative, nurturing side of a woman has a lot to do with what stimulates the heart and soul of her sexuality. It is not always the allure of the “typically” attractive that makes a woman want to get physical. And a woman enjoys a storyline to go with her feelings to give validation for the need to procreate or at least “get into the act”. It actually has nothing to do with the monkeys.

    UGGH. The conclusion of being ‘turned on’ by this was disproved A LONG TIME AGO. The researchers were too CHEAP to compare clitoral erection to penile erection. They just measured vaginal lubrication which, duh, just lubes itself in case of a lot of things. When women’s sexual preferences were tested by measuring the arousal of their homologous organ, guess what? Same as dudes. Read it in Psychology Today.
