A new study of American singles found that during sex with a familiar partner, men have the highest orgasm rates. On average, men experience orgasm 85.1 percent of the time, with their sexual orientation making little difference. For women, however, orgasm occurrence is less predictable. On average, women experience orgasm 62.9 percent of the time during sex with a familiar partner - and this pattern varies with women’s sexual orientation, with lesbian women experiencing orgasm more often than heterosexual or bisexual women.
The Indiana University study, titled “Variation in Orgasm Occurrence by Sexual Orientation in a Sample of U.S. Singles” and published online this week in the Journal of Sexual Medicine, uses a large-scale nationally representative sample to examine how self-identified sexual orientation can affect how often lovers have orgasms.
“These findings may contribute to promotion of more informed sexual health, by reminding us to pay attention to individual variation in research and clinical practice - variation in sexual experiences, variation in sexual identities and variation in sexual outcomes,” said lead author Justin R. Garcia, assistant professor of gender studies and research scientist at The Kinsey Institute. An evolutionary biologist, Garcia is also co-author of “Evolution and Human Sexual Behavior.”
The new study analyzed data from the 2011 wave of the Singles in America study, a now annual survey on the attitudes and behaviors of U.S. singles using nationally representative samples of single men and women ages 21 and older. The Singles in America sample was augmented to provide a better representation of gay men and lesbian women participants. In the current study, respondents were limited to men and women who had sex with a familiar partner during the previous year. It ultimately involved a final sample of 2,850 individuals.
Findings:
Women reported experiencing orgasm 62.9 percent of the time.
Lesbian women reported an orgasm rate of 74.7 percent.
Heterosexual women reported an orgasm rate of 61.6 percent.
Bisexual women reported an orgasm rate of 58 percent.
Men reported experiencing orgasm 85.1 percent of the time, with sexual orientation making no statistically significant difference (gay men 84.7 percent; heterosexual men 85.5 percent; bisexual men 77.6 percent).
“Moreover, to the extent that lack of orgasm is seen as a common and unwanted problem, learning more about orgasm in same-sex relationships may inform treatment for men and women in both same-sex and mixed-sex relationships,” the authors wrote in the article.
What do scientists and clinicians know about orgasms?
Pioneering sex researcher Alfred Kinsey, and later, Masters & Johnson, noted differences in sexual outcomes among heterosexuals, gay men and lesbian women as early as the 1940s and 1950s. Yet little comparative research has been conducted since, leaving gaps in our understanding of sexual outcomes among sexual minorities. Understanding orgasm has implications for research and clinical and therapeutic knowledge involving sexual health and well-being.
Scientists do now know a lot about the psychological and physiological responses involved in orgasm, such as changes that occur in heart rates and blood pressure, and about neural and hormonal changes associated with arousal and climax. What for some can be intense sensations of pleasure are subjective, however, and big gaps remain in what researchers know about orgasm outside the lab. This includes what the researchers describe as “fundamental questions of how demographic factors may contribute to variations in individuals’ orgasm experience.”
There is even disagreement about the purpose of orgasms, with some evolutionary scientists arguing that orgasm is an adaptation to promote reproduction, while other evolutionary theorists such as IU’s Elisabeth Lloyd, a co-author of the current study, argue there is insufficient evidence that such a link exists. Lloyd is author of “The Case of the Female Orgasm: Bias in the Science of Evolution.”
Female Orgasm May Be Tied to ‘Rule of Thumb’
First came the G-spot, then multiple climax and spiritual tantric sex. The modern woman is not only expected to be a good mother and a professional success, but some believe she needs to behave like a porn star in the bedroom.
So if a simple device could reveal whether a woman is capable of a vaginal orgasm, would it take the pressure off heterosexual women to perform?
New research suggests that a simple measurement - a “rule of thumb” - might be the key to the pleasures of sexual intercourse.
About 75 percent of all women never reach orgasm from intercourse alone - that is without the extra help of sex toys, hands or tongue. And 10 to 15 percent never climax under any circumstances.
The Internet is rife with non-orgasmic women who say they are missing out, and statistics suggest that they are a significant group.
“Maybe my boyfriend and I aren’t doing it right or something,” one woman wrote on WebMD.com. “I don’t understand. I feel like less of a woman because I can’t have an orgasm and I want to so bad. I feel incomplete sometimes after sex.”
“I enjoy sex, my partners enjoy the sex,” said another on EmpowHER.com. “The guy I’m with right now is frustrated because he’s never had a problem making a women happy until now, and it’s frustrating for me because I just don’t understand.”
Garcia said the range and variation among women in the current study raises numerous questions regarding the medicalization of orgasm, with women more often than men being diagnosed with orgasmic “disorders.”
Why the range in experiences?
The researchers speculate on the patterns observed, suggesting it could be the result of such known factors as length of a sexual encounter (earlier research points to lesbian women spending more time per sexual session); differences in gendered and sexual attitudes across sexual orientation; and even possible biological factors, such as prenatal exposure to the hormones testosterone and estrogen.
The study authors note that the National Survey of Sexual Health and Behavior, also led by IU researchers, found a correlation between the rate of orgasms for men and women and the variety of sexual behaviors they reported.
Garcia said that partner communication - both spoken and unspoken - can play a big role in shaping sexual experiences and outcomes, including satisfaction.
“Some individuals will say what they want in a sexual encounter, or may be willing to say as much if their partner asked,” Garcia said. “For others, communication may be nonverbal, with body language being key. This may also involve getting to know each other, both in and out of the bedroom, to understand what allows a particular sexual partner to experience a positive sexual outcome.”
Importantly, however, Garcia also notes that orgasm should not be equated with sexual satisfaction, as the two can be quite independent, and that in some instances orgasm is not the goal of a sexual encounter.
The researchers said follow-up studies will look at other demographic factors that could influence rates of orgasm and other sexual outcomes among both men and women.
Can A Woman’s Orgasm Increase Chances Of Pregnancy?
If you’re trying to conceive, you may be wondering if a female orgasm increases the chance of conception.
While a female orgasm certainly feels great and is very beneficial for our emotional and physical wellbeing, orgasm is not essential for conception to occur. One theory (named the ‘up-suck’ theory) was popular amongst some experts – they believed that uterine contractions that resulted from a woman’s orgasm assisted the sperm’s journey to the egg. Unfortunately, an Australian study has found there to be no direct correlation between orgasm and conception.
There are much more reliable ways to increase your chances of pregnancy, including charting your cycle, observing your cervical mucus and having sex on fertile days.
Something that is important to remember is that maintaining intimacy and connection in your relationship is so important. At the risk of making your sex life all about baby making, the best thing to do is go with the flow as far as sex is concerned. Don’t turn loving sex into baby sex. If you have an orgasm or even if you don’t, make sure you’re both always looking for ways to connect with each other in a loving way when trying for a baby. Too much pressure to orgasm or perform, may result in no-one having any orgasms at all - and the last thing you want is for resentment and frustration to build up between you.
