Study of long-term heterosexual couples finds women over-estimate and men underestimate their partner’s sexual advances
“Navigating sexual activity can be difficult, especially when partners’ behaviours that indicate their sexual interest are subtle.”
Imagine that, during a quiet evening at home watching a movie with your romantic partner, you feel intense sexual desire and sensually put a hand on your partner’s thigh. Your partner does not respond and blithely continues to watch the movie… Is your partner truly not interested in sexual activity, or did she/he simply miss your cue?
So begins a new paper, published in the Journal of Social and Personal Relationships, that explores how accurate heterosexual people are at judging their partner’s attempts to initiate sex – in terms of their ability to the spot their partner’s cues, and also their overall impression of how often their partner makes sexual advances. It’s important, because as the researchers, led by Kiersten Dobson at the University of Western Ontario in Canada, note, “Sexual satisfaction is associated with relationship happiness, whereas sexual dissatisfaction is associated with relationship dissolution.”
Other studies have found that in casual, short-term relationships, men tend to overestimate a partner’s sexual interest (while women either underestimate it, or show no bias either way; they’re fairly accurate). An evolutionary psychology explanation for a male tendency to think women are more interested than they actually are is that – in a casual relationship – while incorrectly perceiving interest and being rejected might not feel great, missing the signs of interest, and so a chance to mate, is worse.
To explore what happens in longer-term relationships, the researchers recruited 120 heterosexual couples aged 18-51 (but with a mean age of 22), who had been together for between three months and 30 years.
An initial, exploratory study involved half the couples. The participants all privately completed a battery of questionnaires, which included questions about how often they and their partner attempt to initiate sex and how often they and their partner turn down an opportunity for sex. Then they rated how often these events typically occur over a one-month period (from “never” to “more than 11 times a month”).
Next, they read short descriptions of 29 behaviours that might indicate sexual interest (such as “I put my hand on my partner’s thigh”) and were asked to rate the degree to which they and they partner use each of these behaviours to indicate that they are interested in having sex. The participants also completed questionnaire assessments of their sexual satisfaction and love for their partner.
The results showed that both men and women were pretty good at identifying the behaviours that their own partners use to indicate that they’d like to have sex. However, on average, the women overestimated the number of times that their partner tried to initiate sex, whereas the men got it about right.
A second, similar, confirmatory study, involving the other 60 couples, found that the participants were again pretty good at recognising the behaviours that their own partner uses to indicate interest in having sex. In this group, the women also thought that their partners made more sexual advances than they actually did (according to the partner data), but only marginally. However, the men underestimated their partner’s advances.
Again from an evolutionary psychology perspective, the researchers speculate that for men in a long-term relationship, compared with a casual one, the costs associated with missing the signs of sexual interest may be lower (as there will be plenty more opportunities to have sex) and the costs of rejection will be higher (as being rejected by a long-term partner could be more painful). But as the results from the two studies were in part inconsistent, more work is needed before any firm conclusions on bias can be drawn, they note.
When it came to sexual satisfaction and love, people who overestimated their partner’s sexual advances reported feeling more sexual satisfaction. This might be because they felt more attractive and desired by their partner, the researchers suggest.
On the other hand, people with partners who under-estimated their own advances reported feeling more love and greater sexual satisfaction – perhaps because the under-estimater feels motivated to do something to strengthen the relationship, which may then make their partner feel more satisfied.
As the researchers note, “Navigating sexual activity can be difficult, especially when partners’ behaviours that indicate their sexual interest are subtle.”
The researchers would like to see studies investigating how perceptions – and misperceptions – of sexual advances may affect relationships in the long term. But it would also, I think, be interesting to see a more real-time version of this study. Since other work has found that men under-report their own sexual intentions, it’s hard not to wonder whether the women in this study were really over-estimating their partners’ advances. Asking participants to report back daily, or every time they thought they or their partner had made a sexual advance – and whether or not it led to sex – would surely provide more accurate data than retrospective estimates of what happened in the course of a month.

Health officials in China reported that a man was infected with bubonic plague, the infectious disease that caused the Black Death.
- The case was reported in the city of Bayannur, which has issued a level-three plague prevention warning.
- Modern antibiotics can effectively treat bubonic plague, which spreads mainly by fleas.
- Chinese health officials are also monitoring a newly discovered type of swine flu that has the potential to develop into a pandemic virus.
Bacteria under microscope
needpix.com<p>Today, bubonic plague can be treated effectively with antibiotics.</p><p style="margin-left: 20px;">"Unlike in the 14th century, we now have an understanding of how this disease is transmitted," Dr. Shanthi Kappagoda, an infectious disease physician at Stanford Health Care, told <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">Healthline</a>. "We know how to prevent it — avoid handling sick or dead animals in areas where there is transmission. We are also able to treat patients who are infected with effective antibiotics, and can give antibiotics to people who may have been exposed to the bacteria [and] prevent them [from] getting sick."</p>
This plague patient is displaying a swollen, ruptured inguinal lymph node, or buboe.
Centers for Disease Control and Prevention<p>Still, hundreds of people develop bubonic plague every year. In the U.S., a handful of cases occur annually, particularly in New Mexico, Arizona and Colorado, <a href="https://www.cdc.gov/plague/faq/index.html" target="_blank">where habitats allow the bacteria to spread more easily among wild rodent populations</a>. But these cases are very rare, mainly because you need to be in close contact with rodents in order to get infected. And though plague can spread from human to human, this <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">only occurs with pneumonic plague</a>, and transmission is also rare.</p>
A new swine flu in China<p>Last week, researchers in China also reported another public health concern: a new virus that has "all the essential hallmarks" of a pandemic virus.<br></p><p>In a paper published in the <a href="https://www.pnas.org/content/early/2020/06/23/1921186117" target="_blank">Proceedings of the National Academy of Sciences</a>, researchers say the virus was discovered in pigs in China, and it descended from the H1N1 virus, commonly called "swine flu." That virus was able to transmit from human to human, and it killed an estimated 151,700 to 575,400 people worldwide from 2009 to 2010, according to the Centers for Disease Control and Prevention.</p>There's no evidence showing that the new virus can spread from person to person. But the researchers did find that 10 percent of swine workers had been infected by the virus, called G4 reassortant EA H1N1. This level of infectivity raises concerns, because it "greatly enhances the opportunity for virus adaptation in humans and raises concerns for the possible generation of pandemic viruses," the researchers wrote.
SEAL training is the ultimate test of both mental and physical strength.
- The fact that U.S. Navy SEALs endure very rigorous training before entering the field is common knowledge, but just what happens at those facilities is less often discussed. In this video, former SEALs Brent Gleeson, David Goggins, and Eric Greitens (as well as authors Jesse Itzler and Jamie Wheal) talk about how the 18-month program is designed to build elite, disciplined operatives with immense mental toughness and resilience.
- Wheal dives into the cutting-edge technology and science that the navy uses to prepare these individuals. Itzler shares his experience meeting and briefly living with Goggins (who was also an Army Ranger) and the things he learned about pushing past perceived limits.
- Goggins dives into why you should leave your comfort zone, introduces the 40 percent rule, and explains why the biggest battle we all face is the one in our own minds. "Usually whatever's in front of you isn't as big as you make it out to be," says the SEAL turned motivational speaker. "We start to make these very small things enormous because we allow our minds to take control and go away from us. We have to regain control of our mind."
Is focusing solely on body mass index the best way for doctor to frame obesity?
- New guidelines published in the Canadian Medical Association Journal argue that obesity should be defined as a condition that involves high body mass index along with a corresponding physical or mental health condition.
- The guidelines note that classifying obesity by body mass index alone may lead to fat shaming or non-optimal treatments.
- The guidelines offer five steps for reframing the way doctors treat obesity.
