Casual sex is common, and studies suggest that most people will have it at one point or another. However, despite its prevalence, casual sex is widely misunderstood. Here are nine things science has taught us about casual sex that are worth knowing.Read More
The American Sexual Health Association (ASHA) recognizes February as National Condom Month. For my part in helping to increase awareness of and education about condoms, I’ve put together the following set of 10 interesting facts and statistics. To learn more about National Condom Month, check out this page created by the ASHA.Read More
Many women find man-on-man pornography to be sexually arousing. In fact, one of the world's biggest porn sites--Pornhub--has reported that gay male porn is the second most popular category among female visitors. Many of you may be wondering what it is that draws so many women to it. A recent study published in the journal Porn Studies offers some valuable insight.Read More
Several studies have found that women are more likely to have regrets about their previous experiences with casual sex than men. While men can certainly have regrets about casual sex, they’re more likely than women to regret opportunities they passed up instead of times they actually had casual sex. So why is that? What explains this gender difference?Read More
How many people have had oral sex? Do men and women have similar feelings about this activity? Does oral sex "count" as sex? In this post, we'll take a look at the answers to these and other questions about oral sex.
1.) Most adults in the United States have engaged in oral sex before. A recent, nationally representative survey found that 86-87% of men and women say they have done it at least once.Read More
A reader asked:
“What percentage of men and women actually enjoy giving or receiving oral sex?”
Good question! Let me start by saying that oral sex has become an incredibly common sexual practice in the United States in recent years. In fact, nationally representative survey studies have routinely found that the vast majority of both men and women have engaged in this activity. For example, recent data from the National Survey of Family Growth finds that 86-87% of American adults aged 18-44 have done it at least once (see here for stats on other sexual behaviors).Read More
American sex education courses are seriously lacking when it comes to the subject of women's sexual anatomy and pleasure. Not only are terms like "vulva" and "clitoris" rarely uttered, but students typically learn nothing at all about the female orgasm, which (sadly) explains why so many college students set foot in my human sexuality course asking whether it's even a thing. I kid you not.Read More
February has been declared National Condom Month by the American Sexual Health Association (ASHA). For my part in helping to increase awareness and education about condoms this February, I’ve complied the following list of facts and statistics. To learn more about National Condom Month, check out this page by the ASHA.
1.) With perfect use, condoms are 98% effective at preventing pregnancy. However, perfect use is rarely achieved in the real world due to human error. When we instead consider typical use (or what happens in reality), the effectiveness rate drops to 82%. What this means is that, in practice, 18 out of 100 women who use condoms regularly over the course of a year will end up becoming pregnant.Read More
Why do humans have sex? This is a question few scientists have bothered to ask, probably because the answer seems obvious: pleasure and reproduction, of course. However, research suggests that the answer is more complicated. In fact, when people are actually asked why they have sex, hundreds of unique reasons emerge. Below, we'll take a look at some of the most and least common reasons reported for having sex and consider the ways they’re similar and different across the sexes.Read More
When it comes to teaching American adolescents about sexuality, “we are completely silent around girls' sexual entitlement and girls' pleasure,” says Peggy Orenstein, author of the new book Girls & Sex: Navigating the Complicated New Landscape. But it’s not just that—American culture is sending a message to young women today that “they're supposed to be sexy, that they're supposed to perform sexuality for boys, but that their sexual pleasure is unspoken.”Read More
There are a lot of women out there who find man-on-man pornography to be highly arousing. As some evidence of this, one of the biggest porn websites in the world, Pornhub, has reported that gay male porn is actually the second most popular category viewed by female visitors of the site. This has led many to wonder what it is that draws so many women to this type of porn. A new study published (appropriately enough) in the journal Porn Studies sheds some light on the answer.Read More
What is it about sex that makes it so pleasurable? For many people the answer to this question would seem to be pretty obvious: orgasm. But is that really the case?
In the TEDx video below, sexual psychophysiologist Dr. Nicole Prause suggests that our intuitions here may be incorrect and, further, she challenges us to think differently about what it is that humans find so rewarding about sex.Read More
How do you feel about the first time you had sex? If you pose this question to a bunch of different people, you’re bound to find a range of responses. Some will remember it as incredibly positive and pleasurable, while others will say it was just awkward and uncomfortable. These emotional reactions to our first sexual experiences seem to be important too—studies have found that people who evaluate their virginity loss positively report having more satisfying sex lives than those who look back with anxiety and regret. However, a new study just published in the Journal of Sex Research reports some encouraging news: overall, first-time sex appears to be a more positive experience than it was a few decades ago.Read More
Why do human beings have sex? Surprisingly few scientists have bothered to study this question, likely because it’s one that seems to have an obvious answer: humans have sex for pleasure and for reproduction. But are humans really that simple? Not exactly. In fact, research has found that people report hundreds of distinct reasons for “getting it on!” In this article, I’d like to take a look at some of the most and least common reasons reported for having sex and consider the ways in which they’re similar and different across men and women.Read More
In what is perhaps one of the most well-known psychology experiments of all time, a group of attractive research assistants were instructed to wander around a college campus and proposition students of the other sex . Specifically, the assistant would say “I have been noticing you around campus. I find you to be very attractive,” which was followed by one of three questions: “Will you go on a date with me tonight?” “Will you go back to my apartment with me tonight?” or “Will you go to bed with me tonight?” The results indicated that male and female students responded very differently to these questions.Read More
Every Friday on the blog, I answer people’s questions about sex, love, and relationships. This week’s question comes from a reader who wanted to know whether there’s any truth to the idea that a woman’s vagina becomes “loose” if she has sex frequently.
So I was hanging out with a couple of friends yesterday and they brought up the topic of vaginas in rap music. There seems to be a lot of hype about the elasticity of vaginas or "tight pu**y" in today's rap music, so we were wondering if there is any scientific evidence about vaginas actually becoming more elastic, or "loose," because of continuous sex. Some people said yes others no, so I thought I would ask you.
Every Friday on the blog, I answer people’s questions about sex, love, and relationships. This week’s question comes from a reader who wanted to know more about the relationship between G-Spot and clitoral orgasms.
I know that some women can only experience clitoral orgasm but not G Spot orgasm. I was curious to know if there are many cases of women who are able to have G Spot orgasms but are incapable of orgasming through clitoral stimulation. I'm sure there are a few cases but are these the exception to the rule or is it quite variable?
