10 Surprising Facts About The Vagina

10 Surprising Facts About The Vagina

Although many women and their sexual partners have taken some time to familiarize themselves with the vagina, the reality is that most of us don’t know as much as we should about this fascinating piece of anatomy. Below, I’ve compiled a list of ten of the most interesting facts about the vagina because, well, knowledge is power…and also pleasure.

1. Contrary to popular belief, women who have frequent sex do not develop “loose” vaginas. The vagina naturally becomes looser when women are sexually aroused in order to prepare for intercourse, but after sex, everything goes back to its normal state. What does cause vaginal looseness? Childbirth (sometimes) and older age. Click here to learn more.

Ten Fascinating Facts About The Penis

The penis is a fascinating piece of human anatomy; however, most of us know surprisingly little about it. So, I decided to compile a list of ten of the most interesting facts about the penis. Do you have other favorite penis facts? Feel free to add them in the comments section below.

1. Men usually get 4-5 erections per night, but it's not because they constantly dream about sex--rather, this is simply a natural occurrence as guys enter and exit different sleep cycles. This is why so men wake up with “morning wood.”

Spooning After Sex Might Be Good For Your Relationship

Spooning After Sex Might Be Good For Your Relationship

Post-sex behaviors are highly variable from one person to the next. Some of us spoon or cuddle, some of us go right to sleep, and some of us get up to have a sandwich. But does what you do after sex matter? A new set of studies published in the Archives of Sexual Behavior suggests that, at least for people in relationships, it might. Specifically, the more that couples spoon and express affection after sex, the happier they tend to be.

The Brain In Love (VIDEO)

The Brain In Love (VIDEO)

In this fascinating TED talk, Dr. Helen Fisher explores what happens inside the brain when we experience romantic love. To that end, Fisher describes a series of studies she conducted in which people were put in MRI machines and shown images of their loved ones. The incredible results help to explain why romantic love is such an intense and consuming state, why some couples are able to maintain passion longer than others, and why breakups can be so devastating. Fisher also explores the similarities between romantic love and addiction (for instance, you see tolerance, withdrawal, and relapse in both cases), and even considers parallels to romantic love in the animal kingdom. Check out the full video below for more on the neurochemistry behind love.

A Top 10 List Of The Most Unusual Sexual Turn-Ons

A Top 10 List Of The Most Unusual Sexual Turn-Ons

In a recent survey, I asked readers of this site to describe the most unusual thing they have ever seen that caused them to become sexually aroused. My reason for asking this question was to demonstrate that the nature of sexual turn-ons can be surprisingly diverse. Indeed, we cannot always predict when or why we might become aroused. To that end, below is a list of ten of the most interesting turn-ons from this survey along with the sexual and gender identity of the person who mentioned them.

Why You Shouldn’t Get Your Sex News From Katie Couric

Why You Shouldn’t Get Your Sex News From Katie Couric

Katie Couric recently ran a segment on her show entitled “How To Prevent Your Kids From Watching Porn.” The title of the segment makes the agenda clear: all pornography is damaging to kids and parents need to protect them from it. Couric brought in two experts to discuss this issue, but when one of them (Dr. David Ley, author of The Myth of Sex Addiction) dared to mention that the research examining the effects of porn on kids isn’t so black and white, Couric wasn’t having any of it. For instance, according to Ley:

“There are good research studies that show that adolescents’ use of pornography explains only 2% of the variance in their behavior in relationships, drug use, or behavior problems later on. That’s important. We are over-focusing on pornography because sex, masturbation, and pornography are ‘scary.’”

HIV-Prevention Medications Also Protect Against Genital Herpes

HIV-Prevention Medications Also Protect Against Genital Herpes

Pre-exposure prophylaxis (or PrEP for short) has been in the news a lot lately. In case you are not familiar, PrEP refers to a new method of HIV prevention. Uninfected individuals simply take a medicine known as Truvada daily (Truvada is a combination of two different drugs, tenofovir and emtricitabine). This is actually the same medication used to treat people who are HIV-positive—and it works for them by dramatically lowering the level of the virus in the body (to be clear, this is not a cure--but it does help extend the life of an HIV-positive person significantly). However, when taken by someone who is uninfected, this drug appears to be effective at preventing the virus from ever taking hold. In fact, some studies have found that among individuals who take this drug consistently, their risk of contracting HIV is reduced by as much as 92%! A new study suggests that PrEP may have the positive side effect of protecting against other sexually transmitted infections as well.

6 Fascinating Ways Technology Is Changing Our Sex Lives

However, these are just a few of the many ways that technology and sex are interfacing today. In this post, I’d like to take you on a tour of some of the most interesting new "sexnological" developments.

Why Does The Female Orgasm Exist?

Why Does The Female Orgasm Exist?

Women have the potential to become pregnant whether or not they reach orgasm during vaginal intercourse. This observation has generated a long-standing scientific debate about why women have orgasms in the first place. If the female orgasm is not essential for reproduction, then what purpose does it serve? Although scientists do not yet agree on the answer, a number of interesting theories have been offered.

A Little-Told Tale Of Sex And Sensuality (VIDEO)

A Little-Told Tale Of Sex And Sensuality (VIDEO)

In this fascinating TED talk, Dr. Sheeren El Feki explores the nature of sex and sexuality in the modern Arab world. Of course, most people recognize that the Middle East currently holds pretty conservative sexual values, including the idea that sex is only acceptable within the context of marriage, that a woman's virginity is a matter of family honor, and that matters of sex should not be openly discussed. However, what you may not realize is that this wasn't always the case. In fact, this trend toward sexual conservatism is a relatively recent phenomenon. Check out the video below to learn more.

Why The New Diagnostic Guidelines For Premature Ejaculation Are A Step Backwards

Why The New Diagnostic Guidelines For Premature Ejaculation Are A Step Backwards

What exactly does it mean for a man to ejaculate “prematurely?” This has been a topic of considerable scientific debate for quite some time, with many arguing that the current classification criteria for premature ejaculation are vague and unclear. A new report just published in the Journal of Sexual Medicine attempts to remedy this by proposing what is supposedly an objective, evidence-based definition. However, I have some concerns that the new criteria may end up creating more problems than they solve.

Sex Question Friday: Why Are Straight Guys So Interested In Breasts?

Sex Question Friday: Why Are Straight Guys So Interested In Breasts?

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:

“Why are straight guys into breasts? Does it stem from them having been breastfed as children?”

Great question! I’ve heard this Freudian sort of explanation before (i.e., men’s fondness for breasts stems from having been nourished by their mothers’ breasts as infants); however, I don’t really buy it, nor do most of the other psychologists I know. I mean, if it were true, wouldn’t we expect that women and gay men would be just as sexually interested in breasts?

Does Grindr Really “Lead To Gonorrhea?”

Does Grindr Really “Lead To Gonorrhea?”

So far this year, two studies have been released reporting that use of Grindr and other smartphone hook-up apps is linked to a higher prevalence of sexually transmitted infections among men who have sex with men (MSM). One of these studies was published in January in PLoS ONE (co-authored by yours truly), while the other was published just this month in Sexually Transmitted Infections. The latter study made quite a media splash this past week, generating headlines such as this gem from The Daily Beast: “Grindr-ing Leads to Gonorrhea.” The subtitle for this headline pretty much sums up the current media narrative: “Log on, hook-up, get STD.” So there you have it—smartphone hookup apps cause STDs, right? It sounds like an intuitive conclusion, given the ease with which these apps allow one to locate sexual partners. But is the story really that simple? A closer look at the data suggests that we might want to rethink the notion that these apps cause risky sexual behavior.

Some People’s Brains May Be “Wired” To Seek More Sex

Some People’s Brains May Be “Wired” To Seek More Sex

Whenever you survey people about how many sexual partners they have had in their lifetime, you undoubtedly find a lot of variability. Some people report just one or two partners ever, while others report hundreds or even thousands. How do we account for this incredible range in sexual history? A new study published in Social Cognitive and Affective Neuroscience suggests that it may have something to do with how our brains are “wired” to respond to sexual stimuli.
