In the previous episode, we began a fascinating conversation about the long history of human interest in kink and BDSM. Today, we’re diving deeper into the subject and discussing how major cultural events have played a role in shaping kinky interests. We’re also going to talk about how kink and BDSM have been portrayed in the media and some of the controversies around how it has been presented.

Ever since Fifty Shades of Grey hit the scene, it seems as though kink and BDSM have become ubiquitous in popular media. But here’s the thing: just because kink went mainstream in the last decade or so doesn’t mean that it’s new. In fact, the roots of BDSM trace back centuries. And the history behind it is fascinating, so that’s what we’re going to be talking about today.

Men’s sexuality is often described as being pretty simple. Sex is seen as being easy for guys because they’re always in the mood and sex is just a physical thing for them. The reality of male sexuality, however, is far more complicated, and we’re not doing anyone any favors by oversimplifying it. So in this episode, we’re going to dive into common myths about male sexuality.

In today’s show, we’re revisiting one of my favorit...

How many people have you had sex with? In other words, what’s your “body count?” In this episode, we’re going to dive into the data. We’ll discuss the average number of sexual partners people report having, why men consistently report higher body counts than women, as well as why people seem to place so much emphasis on body count in the first place.

You’ve probably heard the phrase before that “nice guys finish last.” But is there any truth to it? That’s what we’re talking about in today’s show. We’re going to discuss how being overly agreeable has the potential to diminish sex appeal, while also interfering with one’s own sexual pleasure. As my guest today likes to say, nice guys need to learn how to say no sometimes.

“Slut” is a powerful term that has historically been used as an indictment of women’s moral character. And as my guest today explains, as long as terms like this retain their power, we’re never going to have true gender equality in the bedroom. She argues that it’s well past time to reclaim the word slut once and for all, so let’s talk about it.

In today’s show, we’re talking about a new way of treating women’s most common sexual problems. My guest co-developed an online sexual health platform called eSense that’s designed to bring evidence-based treatment for low sexual desire and arousal to the masses at a fraction of the cost of traditional therapy. It could very well be a game-changer in the way we treat sex problems.

The number of adult virgins is growing and is actually at a record high. Many of these folks would like to be having sex, but cannot find a partner. In other words, they are involuntarily celibate, or “incels” for short. So what do we know about these individuals? A deeper look at the psychology of incels reveals a group that is struggling with complex mental health issues.

When women have sex with men, there’s an orgasm gap. However, this gap disappears when women have sex with other women. So why is that? In today’s show, we’re diving into some new research finding that women anticipate sex is going to follow a very different script based on the gender of their partner. It turns out that those scripts have big implications for their odds of orgasm.

In heterosexual relationships, women don’t orgasm as frequently or consistently as men. So why is that? As we’ll explore in today’s show, it’s because there’s an “orgasm pursuit gap.” Sexual scripts lead women to pursue their own orgasms less than men, and to perceive less support from their partners for their own pleasure.
