How Often Do Most Couples Have Sex? 
  
  
  
 As a sexual health doctor, this is the number one question I hear. But it’s not the whole story. 
  
 By Dr. Harry Fisch 
  
  
  
 The number one question I’m asked about sex: how often is normal? 
  
 The average man has eleven erections every day (including partial erections). Teenage boys and men in their twenties with high hormonal levels might think it’s totally normal to have sex several times a day. But in my experience, I’d say that the typical average is two to three times a week. That was also the figure in the American Sexual Behavior Study, a 2006 survey reporting that the average frequency of sex for married couples went from about once every two-three days for couples between the ages of eighteen and twenty-nine, to about twice a week for couples between 30 and 50, and less than once a week for older couples. 
  
 Couples of any age in the early phase of a love relationship tend to have a lot of sex—daily if not more frequently. But the frequency of sex declines as any relationship ages, although married couples have more sex than those who are single. Obviously, regular access to sex makes it more likely to happen! 
  
 Remember, these are averages. Some couples are happy with more frequent sex, some happy with less frequent sex. If you only feel like having sex once or twice a week but find those encounters deeply satisfying, that’s normal for you and that’s totally fine. Not wanting any sex at all is not. 
  
 And that’s really the point: not how much sex you’re having, but whether you and your partner are happy with the sex you are having. Quality wins out over quantity every time. It’s all about the satisfaction. 
  
 That said, quality sex isn’t just about frequency. It’s also about the length of the sex act. 
  
 There have been studies in which couples consented to be scientifically observed having sex, and one of the observers timed each session with a stopwatch to make a fairly accurate assessment about the length of the coupling. Not surprisingly, there is an extremely large variation in the time it takes a couple to have sex, ranging from the excessively short (about two minutes or less, which famed sex researcher Alfred Kinsey dryly noted was a “frequent source of marital conflict”) to the “Are you done yet?” (over forty minutes). 
  
 An astonishing 45 percent of men finish the sex act too quickly, which is to say, within Kinsey’s conflicted two minutes. That’s pretty speedy. Way too speedy for the average woman to be able to have an orgasm through vaginal penetration alone. At least five minutes, and more like seven, is usually what’s needed for a woman to be able to achieve orgasm. 
  
 And even though the average length of the average inter-vaginal sex session is about 7.3 minutes, that’s still not particularly long, especially for women who usually take much longer than men to become aroused enough to have an orgasm. 
  
 So if your man is done within two minutes of things getting hot and heavy—or still not done 40 minutes later—you may want to gently broach the idea of getting a medical checkup to make sure everything’s functioning correctly. And don’t worry: As I discuss in The New Naked, if 7.3 minutes doesn’t seem like enough time for you to get the satisfaction you need, you and your partner can learn to express what you do need or want, so you both can be happy in bed and out.

 Dear Katy Petty, It's Totally Okay to Be Single [Famously] ||||| One hundred and fifty-two heterosexual couples reported their actual and ideal duration of foreplay and intercourse, as well as their perceptions of their partners' desired duration of foreplay and intercourse. Further, participants reported the duration of foreplay and intercourse that they felt most men and most women wanted. Ideal length of foreplay did not differ for men and women. However, men reported a significantly longer ideal duration of intercourse than did their partners. The ideal duration of foreplay and intercourse were significantly longer than the actual duration for both genders. The women, but not the men, significantly underestimated their partners' desired duration of foreplay and intercourse. Further, both genders exhibited faulty stereotypes concerning men's but not women's ideal scripts. Men were seen as desiring a significantly shorter duration of foreplay and intercourse than the ideal reported by the men in the study. Both men's and women's perceptions of their partners' ideal duration of foreplay and intercourse were found to be more strongly related to their own sexual stereotypes than to their partners' self-reported sexual desires, suggesting that people rely on sexual stereotypes when estimating their partners' ideal sexual scripts. Men's and women's ideal scripts and men's and women's sexual stereotypes concerning the opposite gender's ideal duration of foreplay were found to uniquely predict the foreplay performance script. For intercourse, men's and women's ideal scripts and men's stereotypes concerning the duration of intercourse that women want uniquely predicated the performance script. We present potential reasons for the discrepancy in individuals' performance and ideal scripts. ||||| In a piece on Nerve.com, Harry Fisch, author of the new book The New Naked: The Ultimate Sex Education for Grown-Ups, reports that “an astonishing 45 percent of men finish the sex act too quickly.” How quickly? Within two minutes, according to Fisch. This would seem to be bad news for those men's partners and good news for the posthumous reputation of sex researcher Alfred Kinsey, whose research in the 1940s and 1950s concluded that three-quarters of men usually ejaculated within two minutes. 
  
 Before you conclude that Fisch's data simply represents more evidence of a male-dominated society's inherent pleasure inequality, it's worth noting that more recent scholars have looked into the question of what the different sexes actually think about it. As it happens, men may be more bothered by it than women. For a 2004 paper in the Journal of Sex Research, University of New Brunswick researchers S. Andrea Miller and E. Sandra Byers interviewed 152 heterosexual couples on their “actual and desired duration of foreplay and of intercourse.” Their subjects spanned a wide range of ages—21 to 77 years old—and relationship type—from 6-month to 50-year partnerships. Miller and Byers found that men reported a much longer ideal duration than did their partners. 
  
 It's true that for both sexes, the “ideal” length of both foreplay and intercourse was much longer than the actual. But the New Brunswick results at least suggest that the men are not happy with this status quo. 
  
 Fisch also points out that two minutes is “way too speedy for the average woman to be able to have an orgasm through vaginal penetration alone.” But an even older piece of research suggests that link might not be quite so clear. In a 1951 paper in the Journal of Psychology, “Correlates of orgasm adequacy in a group of 556 wives,” psychologist Lewis Terman found no significant correlation between intercourse duration and female “orgasm adequacy.” Alas, the concept of speed has not fared as well in more recent research. In a 2009 paper in The Journal of Sexual Medicine, Czech psychologists Petr Weiss and Stuart Brody found, based on surveys with 2,360 Czech women, that women’s chance of having an orgasm was much more highly correlated with duration of sex than of foreplay. ||||| Where do men last the longest? How sex in New Mexico averages SEVEN minutes - but just 81 seconds in Alaska 
  
  
  
 New Mexico may have to change its state tagline to: 'Where the men last longer'. 
  
 Spreadsheets, an app which measures the 'duration, thrusts, and decibel peak' of a couple's sexual rhythm, looked at the statistics of 10,000 of its users to see how long couples from different states last in the bedroom . 
  
 The Catcus state came out on top with an average intercourse time (excluding foreplay) of seven minutes - compared to just three minutes in New York and 81 seconds in Alaska.

 According to the 2009 study Canadian and American Sex Therapists' Perceptions of Normal and Abnormal Ejaculatory Latencies: How Long Should Intercourse Last?, intercourse lasts anywhere from three to seven minutes on average. 
  
  
  
 'Very few people have intercourse per se [Latin for by thrust] that goes longer than 12 minutes,' explained sex therapist Barry W. McCarthy, adding that premature ejaculation refers to intercourse that lasts less than a minute or two. 
  
  
  
 'Very few people have intercourse that goes longer than 12 minutes' 
  
 The Spreadsheets app, which launched in August last year, aims to help couples measure their pleasure using the accelerometer and microphone in their smartphone to time how long sex lasts, while monitoring both the speed and 'thrust' frequency, as well as the amount of noise created during sex. 
  
  
  
 Users can unlock 30 'achievements ' while using the app, which is a points system enabling couples to set challenges for themselves. 
  
  
  
 A session of early morning sex gets ten points, while a lazy Sunday session earns 20, for example. 
  
  
  
 The app does not record or playback audio or video, and according to the app's homepage, all data is stored securely on a person's mobile device and information is never relayed, backed up, or synced to the internet.

  ||||| STOCKHOLM, Sweden, April 14 (UPI) -- Men who suffered from lifelong premature ejaculation can be treated by pelvic floor exercises over a 12-week period. 
  
 Study leader Dr. Antonio Pastore of the Sapienza University of Rome said the study involved a group of 40 men ages 19 to 46 who had premature ejaculation -- defined as “ejaculation within a minute," who had tried a variety of therapies, without any significant improvement. 
  
 During the 12-week study period, the men were trained to exercise their pelvic floor muscles and their time-to-orgasm was measured. 
  
 The study, presented at the European Congress of Urology in Stockholm, found at the start of the trial the average ejaculation time was 31.7 seconds, but by the end of the 12-weeks of pelvic floor exercises this had risen to 146.2 seconds -- a more than four-fold increase. 
  
 “ 
  
 This is a small study, so the effects need to be verified in a bigger trial. Nevertheless, the results are very positive. The rehabilitation exercises are easy to perform, with no reported adverse effects," Pastore said in a statement. "Previously the men in the trial had tried a variety of treatments, including creams, behavioral therapy, antidepressants and psychological treatments -- with little success. However, we found that 33 of the 40 men in our trial improved their ejaculation time within 12 weeks. We also found that the fact that the men were able to improve their sex-lives through their own efforts helped their self-confidence."

It's not exactly the most romantic statistic: Almost half of all men finish sex within two minutes, reports the New Republic by way of Dr. Harry Fisch's new book, The New Naked: The Ultimate Sex Education for Grown-Ups. In an excerpt published on Nerve, Fisch notes that his patients are typically fixed on what the normal frequency of sex should be, but that quality—and therefore duration—should be of equal concern. He trots out statistics from previous sex studies to that end: that the length of the average sex act is 7.3 minutes, but an "astonishing" 43% of such acts are completed within 2 minutes. This isn't exactly breaking news. Alfred Kinsey determined decades ago that the majority of men ejaculated in 2 minutes or less. (Interestingly enough, a sex therapist recently defined intercourse lasting fewer than 2 minutes as premature ejaculation to the Daily Mail.) But the New Republic points out that men, not women, are probably more likely to be most bothered by the figure. A 2004 study found that men reported a significantly longer ideal duration of intercourse than did women; both sexes had similar ideas about the ideal foreplay length. So what's a guy to do, other than get over it? A Swedish study offers one interesting course of action: Researchers had men who couldn't make it more than a minute complete 12 weeks of pelvic floor exercises; their average ejaculation time rose nearly five-fold, from 31.7 seconds to 146.2 seconds, reports UPI.
