What Counts as “Pornography?” It Depends Who You Ask

What Counts as “Pornography?” It Depends Who You Ask

As a sex researcher, I’ve read a lot of studies on the subject of pornography. One thing that’s been pretty consistent across most of them is that what counts as “porn” is usually left undefined. In other words, when people are asked about their porn usage habits, it’s generally up to them to determine what counts and what doesn’t.

How Long Does It Take Women And Men To Reach Orgasm?

How Long Does It Take Women And Men To Reach Orgasm?

Much has been said and written in the popular media about the length of time it typically takes men and women to reach orgasm; however, most of this information is based on anecdotal reports, not science. So what does research on this subject say? Here’s what scientists have found when they’ve given men and women stopwatches and asked them to record as precisely as possible the length of time it takes them to climax.

Seven Things You Should Know About Bisexuality For LGBT Pride Month

Seven Things You Should Know About Bisexuality For LGBT Pride Month

Bisexuality continues to be a widely misunderstood sexual orientation. Given that this is LGBT Pride Month, I thought it would be useful to put together an article that explores some of the key findings scientists have learned about bisexuality that can speak to some of the biggest misconceptions about it. Here goes:

1.) Bisexuality is real, and it’s not the same as being gay or lesbian. A lot of people deny the existence of bisexuality and assume that everyone who identifies as bisexual is secretly gay; however, the results of several studies reveal that bisexuality involves a distinct pattern of sexual interest and arousal compared to homosexuality.

What Kinds of Porn Do Men and Women Watch Most Often?

What Kinds of Porn Do Men and Women Watch Most Often?

There are lots of articles out there describing the most-viewed porn categories on Pornhub and other popular adult sites—however, that’s not what this article is. While big data insights from major porn websites are certainly interesting and informative in their own right, they are limited in several ways, not the least of which is that we don’t necessarily know how the people who visit those sites are similar to or different from the rest of the population. 

So what happens when—instead of looking at big data—researchers survey people about which types of porn they watch most often?

Why Tinder is Frustrating for Everyone

Why Tinder is Frustrating for Everyone

The internet is rife with articles describing people’s frustration with online dating apps like Tinder. It’s interesting when you think about it because these apps were designed to make dating easier and more efficient than ever; however, they haven’t necessarily made the process more satisfying. One of the problems for those attracted to different genders is that men and women tend to take very different approaches to Tinder—approaches that often end up creating frustration on all sides.

Men And Women Have Different Sexual Regrets

Men And Women Have Different Sexual Regrets

When asked to describe a memorable regret, the things people mention most often involve love, sex, and romance. Common regrets include lost opportunities (like “the one that got away”), cheating and infidelity, and one’s first sexual experience. Men and women both report having sexual regrets, but do the nature of those regrets differ? Research suggests that, on average, they do.

The Truth About the “Oral Sex Gap”

The Truth About the “Oral Sex Gap”

According to countless popular media articles, there is a massive disparity between heterosexual men and women when it comes to giving oral sex. Some of these articles suggest that, in male-female sexual encounters, “blowjobs are basically a given” while cunnilingus is “one of the least-often performed sex acts.” In other words, men are getting oral all the time from women, whereas women are almost never receiving it from men—a situation that has been dubbed the “oral sex gap.”

However, I did some digging into the prevalence of oral sex across genders and it turns out that these claims don’t quite match up with what the research says. The oral sex gap isn’t exactly what we have been led to believe.

How Sexual Attitudes and Behaviors Change as We Get Older

How Sexual Attitudes and Behaviors Change as We Get Older

Sex and aging is a topic that has been underexplored in sexuality research, given that the bulk of sex studies to date have focused on college students. However, we’ve learned more in the last few years, as online data collection and national surveys of sexual behavior have increased. 

One study of sex and aging that recently caught my attention explored how people’s sexual attitudes and behaviors change over the lifespan using data from a large and diverse sample of 1,522 adults from across the United States.

How Many Americans Have Paid For Sex Before?

How Many Americans Have Paid For Sex Before?

Purchasing sex used to be a very common behavior among American men. For example, Alfred Kinsey’s famous studies of human sexual behavior from the 1940s and 50s found that 69% of the men he surveyed had paid for sex at least once! However, more recent studies suggest that the number has dropped significantly as attitudes toward sex outside of marriage have liberalized. In fact, in the 1990s, a nationally representative survey of Americans found that just 16% of men said they had paid for sex before.

So what do the numbers look like today? And how do they compare for men and women?

Sexual Fantasies About Body Fluids: How Many People Have Them?

Sexual Fantasies About Body Fluids: How Many People Have Them?

The human body produces a number of different fluids—and those fluids represent a sexual turn-on for some people. From semen and sweat to blood and breast milk, almost any body fluid you can think of has the potential to become a source of sexual arousal. But just how many people are turned on by each fluid? I explored this question in the data I collected for my book Tell Me What You Want. I surveyed more than 4,000 Americans about their sexual fantasies and, among other things, I asked participants whether they had ever fantasized about several different body fluids.

Forbidden Fruit: How Many of Us Have Fantasized About Our Partner’s Best Friend? Or Their Sibling?

Forbidden Fruit: How Many of Us Have Fantasized About Our Partner’s Best Friend? Or Their Sibling?

In studying the sex fantasies of more than 4,000 Americans for my book Tell Me What You Want, I discovered that there’s one person who’s more likely to appear in our sexual fantasies than anyone else: a current romantic partner (or, if you’re single, an ex-partner). However, our fantasies aren’t only about our partners. For example, sometimes we fantasize about “forbidden fruit”—you know, people our partners might disapprove of, like their best friend or a sibling. Or perhaps we might fantasize about people that our culture or society would consider off-limits, such as someone else who’s married. 

So just how common are these “forbidden fruit” fantasies ? And do they differ based on gender and/or sexual orientation? Here’s a look at what I found when I dug into the data:

Romantic Red: Does Dressing In Red Really Make You More Sexually Attractive?

Over the last decade, scientists have published a series of studies claiming that the color red is a sexual signal and that wearing it makes you more attractive to the other sex. However, a new meta-analysis of the research in this area suggests that this claim may be overblown.

How Many People Want To Have Sex With A Robot?

How Many People Want To Have Sex With A Robot?

I’ve seen a lot of articles lately about sex robots and how they’re supposedly going to revolutionize our sex lives. A lot of these articles make the assumption that there’s a lot of demand and desire for sex robots, but is that really the case? How many people are into the idea of getting it on with a bot anyway? And are robots likely to replace a lot of human-on-human sex?

Sharing and Acting on Group Sex Fantasies: Gender and Sexual Orientation Differences

Sharing and Acting on Group Sex Fantasies: Gender and Sexual Orientation Differences

I surveyed more than 4,000 Americans about their sexual fantasies for my book Tell Me What You Want and I found that group sex was one of the most common things that turned people on, regardless of their gender and sexual orientation. While threesomes were the most popular form of group sex, they were just one of many kinds of group activities that people fantasized about.

In the book, I talk at length about why group sex is such a popular fantasy and what people’s general experiences are like sharing and acting on it. However, when you dig a little deeper into the data, it turns out that the way things go when people share and act on group sex fantasies differs depending upon their gender and sexual orientation. So let’s take a closer look at those results.
