Premature Orgasm Affects Women Too, Study Suggests

According to a new study, a small percentage of women also experience premature orgasm. The research, a survey of Portuguese women, found that 40 percent occasionally came to orgasm faster than they intended during sex. For about 3 percent of women, the problem was chronic. "For this group, female premature orgasm is more than bothersome," said study researcher Serafim Carvalho, of the Hospital Magalhães Lemos in Porto, Portugal.

Contrary to the reassuring catchphrase "size doesn't matter," penis size may matter in bed — but only for some women, and for certain types of orgasms.

A new study finds that women who have frequent vaginal orgasms are more likely than other women to say they climax more easily with men with larger penises.

There's a Sign Women Are Ovulating, But Men Can't Detect It. Women's cheeks get redder when they are the most fertile, but this color change is so subtle that it is undetectable by the human eye, a new study finds.

There's a Sign Women Are Ovulating, But Men Can't Detect It

In the study, researchers in the United Kingdom took photographs of 22 women every weekday over the course of one month. After analyzing the photos, the researchers concluded that the women's faces got redder around the time they ovulated. "This is the first study to conclusively show that women's faces do change in redness over the course of the menstrual cycle," said Robert Burriss, a co-author of the study and a research fellow in psychology at Northumbria University in England. But the researchers had expected to find a change in skin redness that was detectable to the human eye, because this might explain why previous studies had suggested that men perceive women's faces as more attractive when the women are ovulating, Burriss told Live Science.

That pleasurable, tingling ache of sexual arousal can quickly turn torturous when it never ends.

New Clue to Constant Sexual Arousal in Women

An unknown number of women suffer from the constant sensations of persistent genital arousal disorder, which has no cure, and no known cause. But now researchers at Rutgers University say they've uncovered a clue: a small study showed a disproportionate number of women with persistent genital arousal disorder (or PGAD) have tiny growths called Tarlov cysts along their lower spines. "This is the very first connection that's been made between Tarlov cysts and PGAD. Many doctors haven't heard of either condition," said Barry Komisaruk, lead author of the study published May 17 in the Journal of Sexual Medicine. Pansexual: A 'New' Sexual Orientation?

Heterosexual, homosexual, bisexual — these are terms with which most people are familiar, but they aren't the only sexual orientations that exist in today's world.

Pansexual: A 'New' Sexual Orientation?

Pansexual, a relatively new category of sexual identity, is characterized by physical or romantic attraction to others, regardless of their gender identity or biological sex. Pansexuality — sometimes known as omnisexuality — is derived from the Greek prefix pan-, meaning "all. " As such, pansexuals may be attracted to those of all biological sexes or gender identities — including men, women, those who don't identify with a specific sex or gender or those who are transsexual or transgender. This differentiates pansexuality from bisexuality, which denotes attraction to people of just two different sexes — male and female. The term has since been reclaimed by those who wish to connote their recognition of the fluidity of gender and their belief that there are more than two genders.

Surviving Infidelity: What Wives Do When Men Cheat

Eliot Spitzer as he announced his resignation to a room full of reporters. When the cameras stopped flashing, however, a husband and wife were left to deal with an alleged violation of marriage and above all, busted trust. Gov. Spitzer has referred publicly to the alleged infidelity as a "private matter," but the experience is rooted in human behavior and family sociology. Why Men and Women Get Jealous for Different Reasons. Cheating on a spouse or significant other is sure to cause feelings of jealousy and hurt in the spurned partner.

Why Men and Women Get Jealous for Different Reasons

But men and women differ on what part of cheating they think is the worst: Men tend to be more bothered by sexual infidelity, while most women are bothered more by emotional infidelity. The prevailing explanation for this difference is the unique evolutionary roles played by men and women, but a new study suggests that it has more to do with the types of attachments people form in relationships. The widespread evolutionary explanation posits that men rank sexual infidelity as the greater sin because over the eons they learned to be hyper-vigilant about sex, as they could never be absolutely certain that their children were actually theirs. Women, on the other hand, became more bothered by emotional infidelity, because they are concerned about having a partner to help raise their children. 5 Ways Relationships Are Bad for Your Health. On Valentine's Day, the sight of couples holding hands and exchanging kisses might unleash a wave of jealousy in those who are single.

However, there might not be much to be jealous about. Relationships can be fraught with sadness, anger, confusion and stress. What Falling in Love Does to the Brain. Falling in love can wreak havoc on your body. Your heart races, your tummy gets tied up in knots, and you're on an emotional roller coaster, feeling deliriously happy one minute and anxious and desperate the next. Research shows that these intense, romantic feelings come from the brain.

In one small study, researchers looked at magnetic resonance images of the brains of 10 women and seven men who claimed to be deeply in love. The length of their relationships ranged from one month to less than two years. Participants were shown photographs of their beloved, and photos of a similar-looking person. Bionic Humans: Top 10 Technologies. The History of Pornography No More Prudish Than the Present. Pornography is often portrayed as one of the ills of today's society, evidence of modern moral decay brought to you by video cameras and broadband access. As it turns out, modern times have got nothing on the past. Pornography existed long before video or even photography, and many researchers think evolution predisposed humans for visual arousal (It's a lot easier to pass on your genes if the sight of other naked humans turns you on, after all).

Whichever way you slice it, the diversity of pornographic materials throughout history suggests that human beings have always been interested in images of sex. Lots and lots of sex. Pot Use May Mellow Out Men's Sexual Function. Marijuana users sometimes report that pot enhances their desire for sex. But a new review of research on marijuana and sexual health suggests that male smokers could be courting sexual dysfunction. Research on the topic is contradictory and few studies are high-quality, said study researcher Rany Shamloul, a physician with appointments at the University of Ottawa and Queen's University in Canada as well as the University of Cairo. But recent research – including the finding that the penis contains receptors for marijuana's active ingredient – suggests that young men may want to think about long-term effects before rolling a joint, Shamloul told LiveScience.

5 Ways Love Affects the Brain. By Tanya Lewis, Staff Writer | February 14, 2014 11:04am ET Credit: umnola, Shutterstock "Love looks not with the eyes, but with the mind," as Shakespeare's Helena said in "A Midsummer Night's Dream" — and perhaps neuroscientists would agree. Love might seem to move in mysterious ways, but scientists actually have a pretty good idea of what love does to the brain. Being in love floods the brain with chemicals and hormones that produce feelings of pleasure, obsession and attachment. Delaying Sex Makes Better Relationships, Study Finds. Delaying sex makes for a more satisfying and stable relationship later on, new research finds. Couples who had sex the earliest — such as after the first date or within the first month of dating — had the worst relationship outcomes.

"What seems to happen is that if couples become sexual too early, this very rewarding area of the relationship overwhelms good decision-making and keeps couples in a relationship that might not be the best for them in the long-run," study researcher Dean Busby, of Brigham Young University's School of Family Life, told LiveScience. Busby and his colleagues published their work Dec. 28 in the Journal of Family Psychology.

The study was supported by research grants from the School of Family Life and the Family Studies Center at Brigham Young University, which is owned by The Church of Jesus Christ of Latter-day Saints, or the Mormon Church.
