Sexless Marriages: How Common Are They, And How Do People Cope With Them?

Sexless Marriages: How Common Are They, And How Do People Cope With Them?

Nationally representative U.S. survey data reveal that approximately 1 in 7 adults today are living in a sexless marriage, meaning they report engaging in little to no sexual activity [1, 2]. Despite how common sexless marriages are, surprisingly little research exists on the topic. So why does sexual activity decline in so many couples in the first place and how does it affect the partners? Also, what are the factors that might lead people to stay in sexless marriages despite the fact that the experience tends to be highly distressing?

Living Together Before Marriage Doesn't Doom Relationships After All

Living Together Before Marriage Doesn't Doom Relationships After All

When I was a graduate student studying the psychology of romantic relationships, I remember learning about “the cohabitation effect” in a few of my courses. Relationship scientists coined this term to describe the increased risk of divorce that seemed to accompany living together before marriage. At the time, several studies had been published in major journals supporting this idea.

Interestingly, however, recent studies suggest that “the cohabitation effect” is a thing of the past—and may have never even existed at all.

When are Married Couples Most Likely to Cheat? The Link Between Infidelity and Relationship Length

When are Married Couples Most Likely to Cheat? The Link Between Infidelity and Relationship Length

I shared an article on Twitter the other day about the prevalence of infidelity, which prompted a response from my pal Dan Savage about how cheating is associated with the length of a relationship. Basically, he wanted to know whether cheating is more or less common when you look at couples that have been together for a very long time. This is an interesting question and one that I’ve actually never been asked before, so I did some digging and here’s what I found. It turned out to be a pretty interesting story.

Can Food Put Us In The Mood? How Hunger State Influences Responses to Romantic Imagery

Food and romance are intimately intertwined in modern dating rituals. Indeed, restaurants are one of the most popular places people visit when they go on a date. Neuroscience research suggests that there might be a very good reason for this: having a full stomach just might make our brains more sensitive to romantic cues.

How the Practice of BDSM is Linked to Relationship Satisfaction

How the Practice of BDSM is Linked to Relationship Satisfaction

People who are into bondage, discipline, dominance, submission, sadism, and masochism (or BDSM for short) experience a lot of stigma. For one thing, they are often seen as psychologically disturbed, despite research showing that BDSM practitioners appear to be just as psychologically healthy as everyone else. For another, many people—including a lot of mental health professionals—question whether you can practice BDSM and still have a healthy relationship. In fact, in one survey of therapists, fully one-third of them reported being unsure of whether someone into BDSM could carry on a functional relationship [1].

Swingers And Polyamorists May Have More Satisfying Sex Lives Than Monogamists

Swingers And Polyamorists May Have More Satisfying Sex Lives Than Monogamists

There’s a common assumption that monogamous relationships are superior to consensually non-monogamous relationships in virtually all ways. In fact, studies have found that monogamous relationships are thought to be better in terms of promoting closeness, trust, intimacy, companionship, and communication [1]. However, the presumed benefits don’t stop there—monogamous relationships are assumed to be more sexually satisfying, too, because it’s presumed that people who open their relationships are only doing so because they’re unhappy in some way.

So is it really the case that monogamists necessarily have better sex lives and relationships overall compared to those who are in consensually non-monogamous relationships? Do the stereotypes reflect reality? Let’s take a look at the research.

When People Cheat, Who Do They Do It With? Is It Usually A Friend Or A Stranger?

When People Cheat, Who Do They Do It With? Is It Usually A Friend Or A Stranger?

There’s a lot of research out there looking at how many people have cheated, their reasons for cheating, and what “counts” as cheating; however, surprisingly little work has looked at who people are actually having sex with when they commit infidelity. Is it usually with someone they know, or with a stranger? And does this differ for men and women? A new study published in the Journal of Family Psychology offers some answers.

How Is Porn Use Linked To Relationship Satisfaction? It’s Complicated

How Is Porn Use Linked To Relationship Satisfaction? It’s Complicated

It’s easy to find articles in the popular media talking about how porn ruins relationships. Many scientific studies have made this claim, too. However, there’s a problematic assumption embedded in most of these writings, which is that porn affects all people the same way. That’s not a very good assumption to make.

When it comes to something like porn, different people are going to be affected by it in different ways because of their unique psychological profile. Some of us are predisposed to view porn (and its effects) in a negative light, whereas others are predisposed to view it in a positive light. A new study published in the Journal of Sex Research offers support for this nuanced view of the effects of porn on relationships.

What the Most Sexually Satisfied Couples are Doing in (and Out of) Bed

What the Most Sexually Satisfied Couples are Doing in (and Out of) Bed

What keeps passion alive in a long-term relationship? According to a recent study of nearly 40,000 adults (all of whom were heterosexual and currently in romantic relationships), there were five key differences between people who said they were able to keep the passion going and those who weren’t. People who kept the spark alive were more likely to (1) spend time setting the mood, (2) practice sexual communication, (3) receive oral sex, (4) be happier with their relationship in general, and (5) engage in more acts of sexual variety.

While there’s a lot to be said about each of these factors, I want to focus on just one of them in this post—the role of sexual variety.

A recent study published in the Journal of Sex Research identified eight distinct motivations people can have for cheating (read all about those motives here).

Here’s a quick review of the key findings.

How Do Monogamous And Consensually Non-Monogamous Relationships Compare? (Video)

How Do Monogamous And Consensually Non-Monogamous Relationships Compare? (Video)

Studies have found that people overwhelmingly rate monogamous relationships as superior to consensually non-monogamous relationships on virtually every dimension you can think of [1]. For example, monogamy is seen as promoting better relationship quality in terms of enhancing intimacy, safety, honesty, and communication. Even on qualities that have nothing to do with relationship functioning, such as paying taxes on time and taking a daily multi-vitamin, monogamy is seen as better for promoting them. Do people’s perceptions match up with reality, though? Are people in monogamous relationships necessarily much better off?

Is Watching Porn a Form of Infidelity?

Is Watching Porn a Form of Infidelity?

What “counts” as cheating on a romantic partner? It depends who you ask. Research finds that people define infidelity in very different ways. However, there are some things that people seem to agree on more than others.

For example, people largely agree that having sexual intercourse with someone who isn’t your partner is a form of cheating (assuming, of course, that you agreed to be monogamous with that partner). The same goes for taking a shower with another person or sending them naked photos. But what about just watching porn by yourself? Do people typically categorize that as a form of infidelity? A recent study published in the Archives of Sexual Behavior offers some insight into this question.

Can You Really Fall In Love At First Sight?

Can You Really Fall In Love At First Sight?

A lot of people claim to have had experiences with the phenomenon of “love at first sight.” But is it really possible to fall in love with someone instantaneously? Believe it or not, social scientists really haven’t bothered to test this idea until now. A new set of studies published in the journal Personal Relationships suggests that people who report having fallen in love at first sight probably weren’t actually in love. Truth be told, they were probably in lust instead.
