Sex Research News

YouGov Poll Finds That Nearly 1/2 of Men and 1/3 of Women Want To Be In Some Sort of Open Relationship

  • The first bit of sex-related news we covered today isn’t from a scientific study–instead, it’s a survey conducted by YouGov, which polls Americans on all sorts of issues. In this survey, 1,000 American adults were asked about their experiences in relationships.
  • Specifically, they were asked whether their current relationship was monogamous or non-monogamous, and whether their IDEAL relationship would be monogamous or non-monogamous.
  • Results showed that about 2/3 (66%) of men and a little over 3/4 (76%) of women were currently in a completely monogamous relationship, which suggests that 1/3 of men and 1/4 of women are in some sort of non-monogamous relationship.
  • In terms of ideal relationship, 44% of men and 30% of women wanted something other than a completely monogamous relationship.
  • However, this doesn’t mean they wanted a completely open situation–only about 8% of men and 7% of women wanted total nonmonogamy, suggesting that for most of the non-monogamy crowd, an ideal relationship would be one that’s monogamish.
  • So, what were some correlates of being interested in a non-monogamous relationship?
    • Being younger (under 30) vs. older (over 65)
    • Being Black or Hispanic vs. White
    • Being Democrat vs. Republican
    • Living in the Northeast
    • Interestingly, there was NO difference based on family income.
  • The takeaway? A LOT of Americans want to be practicing non-monogamy, and that number is higher than the amount that are currently doing so.

Are Boob Size Preferences Universal?

  • Is there such thing as a universally appealing breast size? A new study sought to answer this question by getting the preferences of men from four very different cultures–Brazil, Cameroon, the Czech Republic, and Namibia.
  • Results showed that a small majority of the total sample preferred medium-sized breasts, followed by large sized, but overall there was wide cultural and individual variability in preferences.
  • What WAS universal, however, was breast firmness–the vast majority of men from all four countries preferred firm breasts. So why was firmness universal but size was not?
  • Well, it has to do with evolution. In terms of reproductive success, medium-sized breasts are just as good at feeding as are large breasts. Breast firmness, however, is correlated with how many kids a woman has already had, so it signifies her residual fertility.
  • The takeaway? A preference for big boobies isn’t universal, so if you do like them it has more to do with your own individual preference than with those of your culture or gender.

Does Parental Sexual Orientation Matter for the Development of Adopted Kids?

  • Do kids adopted by gay parents fare worse than kids adopted by straight parents? To find out, the authors of this new longitudinal study followed 96 heterosexual and lesbian/gay families with kids adopted in infancy from adoption up to school-age.
  • When asked about school-age kids’ psychological adjustment, family functioning, and health and happiness, results showed that there were no differences on any of these measures based on whether kids had gay or straight adoptive parents.
  • What DID make a difference was how much stress the parents were experiencing. The more parents experienced stress early on, the more kids were suffering when they were school-age.
  • The takeaway? Children’s healthy development depends upon healthy family functioning more so than on family structure, and there are no real disadvantages for kids of gay vs straight parents.

Kinsey Data Reveals That Teen Girl-Adult Woman Sex is Reported as Positive Rather Than Traumatizing Experience  

  • The current study took a look at the old Kinsey data collected throughout the U.S. between 1939 and 1961, with a focus specifically on girls who said their first sexual experience was before the age of 18 and with a woman.
  • The study assessed age of the girls and their partners, as well as reactions to teen-adult sex vs. teen-teen sex and adult-adult sex.
  • Results showed that girls <18 whose fist same-sex sexual experience was with an adult woman reacted just as positively as girls <18 whose first same-sex sexual experience was with a peer and as adult women whose first same-sex sexual experience was with another adult woman. For all three cases, positive reactions were very high–85%, 82%, and 79%, respectively.
  • Furthermore, none of these girls and few of these women reported any negative reactions (e.g., fear, disgust, shame, regret).
  • The takeaway? Minor-adult sex is not inherently traumatic, especially compared to age-concordant sex. Interestingly, these findings corroborate those found in the Kinsey male-male sample!

Sex Toys/Products Highlights

zhana1This week we highlighted the Aneros, a sex toy for men. The Aneros is designed to stimulate the prostate, which is a gland inside a man’s anus that feels amazing when pressed on. You can use the Aneros by holding the plastic handle to push the toy up and down inside your or your partner’s ass. There’s also a great part at the bottom of the toy that pushes against the taint (perineum) for ultimate pleasure.

Get the Aneros now at my favorite sex store The Pleasure Chest with free shipping (to most countries) for all orders over $75! Or if you live in NYC, LA, or Chicago, check out one of their gorgeous stores and do some in-person shopping! They also have great sex education workshops you might want to check out.



Audience Question

How many times a day is it “good” to masturbate?

Well, there’s no one number! You can masturbate however much you want so long as it doesn’t interfere with the rest of your life. Once a day is a good rule of thumb but there are a lot of things that might make you want to masturbate more or less, such as whether you’re having sex regularly or whether you’re ovulating vs. on your period. In short: it depends!


Until next time,

Dr. Zhana

  • A New Study Explains Why Many Lesbians Are Biased Against Bisexual Women

    Bisexual folks commonly fall victim to the “double stigma” surrounding their sexual orientation. Compared to heterosexuals, lesbian and gay folks still have more positive attitudes towards bisexual people, but compared to other gay, lesbian, queer, bisexual, asexual and pansexual people, lesbians and gay men harbor the most bi-negativity. “So, why are many lesbians so anti-bi? A new study recently published in the journal Psychology of Sexual Orientation and Gender Diversity suggests that this might be due to what the researchers call the androcentric desire hypothesis: The fact that people (gay men and lesbians alike) perceive bisexuals as being more sexually attracted to men

  • Study Finds Queer Folks Are 20 Times More Likely to Be Activists Than Cishets

    Lesbian, gay, and bisexual people are more likely to be activists in more than just the LGBT movement, according to recent research. It wouldn’t come as a surprise that people are most likely to engage in activism for their own group: There are far fewer men than women at feminist rallies, for example, and far fewer heterosexuals than queer folks at pride marches. But is there some crossover between social movements? In other words, are people who belong to one stigmatized group more likely to be also active in social movements that primarily affect other stigmatized groups? A new study using a
