Episode 190: Women Who Stray – The Rise of Female Infidelity
Rates of infidelity have risen over the last half-century; however, if you break the data down by gender, it turns out that men’s rate of infidelity has remained relatively stable, whereas women’s has increased. So what’s behind the rise in female infidelity? And what are the implications of this for modern-day marriages and relationships? Let’s talk about it!
I am joined today by author Susan Shapiro Barash. She has written thirteen nonfiction books on women’s issues. She also writes fiction under her pen name Susannah Marren. Susan’s latest book is titled A Passion for More: Affairs that Make or Break Us. In this book, Susan presents three decades of research she conducted on heterosexual women in monogamous relationships who committed infidelity.
Some of the specific topics we discuss include:
Are women today actually cheating more, or are they just more willing to admit to it than they were in the past?
What role does technology play in women’s infidelity?
How is age related to having an affair among women?
In what ways do women say that affairs made their relationships or marriages better?
At what point do affairs become a catalyst to leave a relationship?
Be sure to check out Susan’s website to learn more.

Episode 189: What Asexuality Is, And Isn’t
Asexuality is a broad umbrella term that refers to individuals who do not experience sexual attraction to others, or who only do so under rare or limited circumstances. Growing research in this area is helping to shed important light on the nature of asexuality because there are a lot of misconceptions about it, such as the idea that asexuality is a sexual dysfunction. But that’s not the case—and that’s what we’re going to be talking about today. We’re going to be exploring a new study that looks at sexual arousal and response in asexual men. The results are fascinating and help to give us a better understanding of what asexuality is and is not.
I am joined once again by Dr. Malvina Skorska, a Postdoctoral Fellow at the University of Toronto Mississauga and at Brock University. She is also in training to become a psychotherapist in order to bridge both research and clinical work. Her research focuses on sexual orientation and gender dysphoria and has been published in leading scientific journals.
Some of the specific topics we discuss include:
How is asexuality defined scientifically?
Why is it important to study asexual person’s sexual response and function?
What can studying asexual persons’ sexual response and function tell us about the nature of asexuality?
When showing people erotic films, how are asexual men’s sexual responses similar to or different from those of gay and heterosexual men?
How are the fantasies of asexual men different from men of other sexual orientations?
What do we know about sexual arousal and response in asexual women?
Be sure to check out Malvina’s website to learn more.

Episode 188: Where Does Our Sexual Orientation Come From?
Where does a person’s sexual orientation come from? Hundreds, perhaps thousands, of studies have attempted to answer this question. This research suggests that there isn’t a simple explanation and that two people might develop the same sexual orientation for very different reasons. In today’s show, we’re going to talk about the current state of the science, including what we know about the roles of immunological, hormonal, and genetic factors. We’re also going to discuss why we know less about the development of sexual orientation in women than in men, as well as some of the complexities inherent in studying the origins of human sexuality.
My guest is Dr. Malvina Skorska, a Postdoctoral Fellow at the University of Toronto Mississauga and at Brock University. She is also in training to become a psychotherapist in order to bridge both research and clinical work. Her research focuses on sexual orientation and gender dysphoria and has been published in leading scientific journals.
Some of the specific topics we discuss include:
Why is it important to study how sexual orientation develops?
How is sexual orientation defined in scientific research, given that sexual attraction, behavior, and identity do not overlap perfectly?
Why are men with more older brothers more likely to be gay?
How is testosterone exposure in the womb related to sexual orientation?
Is there such a thing as a “gay gene?”
Be sure to check out Malvina’s website to learn more about her work.

Episode 187: “Out of Control” Sex – Compulsive Sexual Behavior Disorder
Some adults feel highly distressed about their porn use. In most of these cases, the root cause of the problem can be traced back to shame or moral conflicts surrounding porn. At the same time, however, not all porn problems stem from moral issues. For some folks, the problem is that they have what’s known as compulsive sexual behavior disorder, which involves “out of control” behavior relating to porn use or other sex acts. This is the final installment of a four-part series on the science of porn and, today, we’re going to do a deep dive into compulsive sexual behavior.
I am joined once again by Dr. Joshua Grubbs, a clinical psychologist and associate professor in the Clinical Psychology program at Bowling Green State University. Josh will soon be joining the faculty in the Clinical Science PhD Program at the University of New Mexico and the Center for Alcohol, Substance use and Addiction. He conducts research on addiction, personality, and morality, he has published more than 100 peer-reviewed articles.
Some of the specific topics we discuss include:
Compulsive sexual behavior, hypersexuality, and sex addiction are all terms that get thrown around when people report problems stemming from porn use. Which one should we be using?
What might compulsive sexual behavior disorder look like in everyday life?
What constitutes “too much” when it comes to porn use or sex?
How common is compulsive sexual behavior? Is there a gender difference in it?
What might a typical treatment approach look like for compulsive sexual behavior?
Learn more about Josh on his website, and follow him on Twitter @JoshuaGrubbsPhD.

Episode 186: Men Who Use the Least Porn Have the Most Porn Problems
Research on pornography’s effects points to a fascinating paradox: the people who report the most problems stemming from porn use are often the ones using the least porn! How is that possible? That’s what we’re going to be discussing today. This is the third installment in a four-part series on the science of porn. In this show, we’re going to dive into what’s known as moral incongruence, which is when people engage in sexual behaviors, like porn use, that conflict with their moral values. We’re also going to explore how porn affects both religious and non-religious persons, as well as how therapists treat problems relating to moral incongruence.
I am joined by Dr. Joshua Grubbs, a clinical psychologist and associate professor in the Clinical Psychology program at Bowling Green State University. Josh will soon be joining the faculty in the Clinical Science PhD Program at the University of New Mexico and the Center for Alcohol, Substance use and Addiction. He conducts research on addiction, personality, and morality, he has published more than 100 peer-reviewed articles.
Some of the specific topics we discuss include:
What is meant by the term “moral incongruence” and what are some of the ways that this might play out?
How is moral incongruence related to whether individuals self-identify as “porn addicts?”
Do religious people have more porn problems than non-religious people, or do their problems just stem from different causes?
What is the impact of moral incongruence on people’s sex lives and relationships?
Clinically, how do you help a person who experiences a conflict between their sexual interests and personal values?
Learn more about Josh on his website, and follow him on Twitter @JoshuaGrubbsPhD.

Episode 185: The Problem With Porn “Reboot” And Recovery Programs
The growing anti-porn movement has fueled the rise of an entire industry centered around selling people on the idea of masturbatory abstinence. Often referred to as a “reboot,” these programs encourage men to forego self-pleasure and orgasm for prolonged periods of time, which they say is necessary to reset the brain and boost testosterone. But do these programs work as advertised? This is the second installment in a 4-part series on the science of porn and, today, we’re going to go inside the world of porn addiction recovery programs.
I’m joined once again by Dr. Nicole Prause, a licensed psychologist and sex researcher, founder of the sexual biotechnology company Liberos, and a scientist in the Department of Medicine at UCLA. Nicole has studied the experiences of hundreds of men who tried reboot programs, and the results suggest that these programs may actually be causing harm and taking a toll on men’s mental health.
Some of the topics we discuss include:
Where is the rise in anti-porn sentiment coming from?
What might a typical reboot program look like?
What does a “relapse” mean in the context of a reboot? How common is this kind of relapse?
How do men engaged in reboot programs fare in terms of their mental health and sexual function?
For individuals who feel distressed about their porn usage, what can they do?
Learn more about Nicole and her work over at Liberos and follow her on Twitter @NicoleRPrause.

Episode 184: The Truth About “Porn Addiction”
How does porn affect us? And are people becoming “addicted” to it? Today, we’re going to begin a four-part series on the science of porn to better understand its effects. For our first show, we’re going to discuss why different studies of porn have yielded different conclusions, why porn shouldn’t be thought of as addictive in the same way that drugs are, whether there’s a link between porn and sexual violence, as well as how we can have more productive conversations about pornography.
I’m joined by Dr. Nicole Prause, a licensed psychologist and sex researcher who founded the sexual biotechnology company Liberos. She is a former Kinsey Institute trainee and has published an extensive body of research on the neuroscience and psychophysiology of sex. She is currently a scientist at the University of California, Los Angeles in the Department of Medicine.
Some of the topics we discuss on this show include:
What counts as porn anyway, and how can you accurately measure porn use on surveys when different people hold different definitions of porn?
Why are there so many discrepant findings in the scientific literature about pornography’s effects?
Why shouldn’t we think of porn as addictive? How should we think of it instead?
When people identify porn as a problem in their lives, is porn per se really the issue or is there something else going on?
In what ways can porn potentially have positive effects on people?
Learn more about Nicole and her work over at Liberos and follow her on Twitter @NicoleRPrause.

Episode 183: How Atlanta Became a Southern Hub For Vice
Although the Southern United States is often seen as a bastion for conservative sexual values, it has a very deep and rich sexual history worth exploring, especially when you consider a city like Atlanta. Often described as “the strip club capital of America,” Atlanta has long been a home to sex work, as well as LGBTQ nightlife. And these “vice” establishments actually played a vital role in the city’s tremendous growth, both as a place to live and visit. In today’s show, we’re going to pull back the cover on Atlanta’s fascinating sexual history.
I am joined once again by writer and historian Martin Padgett. His is the author of A Night at the Sweet Gum Head, which tells the story of Atlanta’s gay revolution in the 1970s. He is also working on a new book titled The Many Passions of Michael Hardwick, which tells the story of what is arguably the most important gay rights case in history.
Some of the topics we discuss include:
How did a burgeoning sex scene develop in in the middle of what has historically been a very conservative state?
How did the sex scene it Atlanta set the stage for the city’s growth?
What made Atlanta a popular home and destination for the LGBTQ community?
How did the nightlife scene in Atlanta help to galvanize the gay rights movement?
How can visiting so-called “vice” establishments also be a virtue in terms of promoting self-acceptance and sex-positivity?
Find out more about Martin on his website.

Episode 182: Could Sodomy Laws Come Back?
Until 1960, sodomy was illegal throughout the entire United States. While this technically made oral and anal sex illegal for everyone, these laws were largely enforced only when sodomy occurred between persons of the same sex. Sodomy laws have since been repealed in most states and, since 2003, they are no longer enforceable anywhere in the country. But does this mean that sodomy laws are gone for good? In the wake of the Roe v Wade reversal, one Supreme Court justice called to revisit the issue, which is setting off alarm bells. So today’s show is all about the past, present, and future of sodomy laws.
I am joined by writer and historian Martin Padgett. His is the author of A Night at the Sweet Gum Head, which tells the story of Atlanta’s gay revolution in the 1970s. He is also working on a new book titled The Many Passions of Michael Hardwick, which tells the story of what is arguably the most important gay rights case in history.
Some of the topics we discuss include:
The story of Michael Hardwick, who was arrested for having consensual sex with another man in the 1980s and appealed his case to the highest court in the land.
The 1986 Bowers v Hardwick Supreme Court case that upheld sodomy laws.
The 2003 Supreme Court case that declared sodomy laws unconstitutional.
How the reversal of sodomy laws paved the way for same-sex marriage and non-discrimination laws.
Current attempts to revive old laws that infringe on sexual and reproductive freedom.
The future of sodomy laws in the U.S.

Episode 181: Attachment Styles and Consensual Non-Monogamy
Nationally representative surveys of North American adults have found that about 1 in 5 people say they’ve been in a sexually open relationship at some point, with an even larger number expressing interest in this relationship style. So what makes people more vs. less interested in consensual non-monogamy (CNM)? In today’s show, we’re going to look at how different attachment styles are related to CNM interest and experience. We’re also going to explore the roots of the stigma against sexually open relationships, as well as how this stigma affects CNM partners.
I am joined once again by Dr. Amy Moors, an Assistant Professor of Psychology at Chapman University. Her research focuses on sexuality, consensually non-monogamous relationships, and LGBTQ+ issues. Amy has published more than 55 journal articles and book chapters, and has received several awards for her pioneering research on polyamory.
Some of the topics we discuss in this episode include:
How is avoidant attachment related to consensual non-monogamy? What about anxious attachment?
How is the structure of polyamory (i.e., hierarchical vs. non-hierarchical) related to attachment style?
Why do so many people seem so convinced that consensual non-monogamy just can’t work?
How can polyamorous individuals identify healthcare providers who are affirming?
How are attitudes toward polyamory and CNM more broadly changing?
Check out more about Amy and the ONWARD Lab on her website, and be sure to follow Amy on Twitter @ACMoors.
Thank you to our sponsors!
Researchers at Ball State University are currently recruiting participants for a study examining the experiences of individuals in at least one polyamorous relationship. If you are (1) age 18 years or older, (2) currently identify as polyamorous, and (3) are part of at least one consensual polyamorous relationship, visit https://bsu.qualtrics.com/jfe/form/SV_3k3QXZnrXX3rCCy to participate. The survey should take no longer than 45 minutes and you will have an equal opportunity to receive one of forty (40) $25 Tango gift cards for your voluntary participation.
