Interesting Facts About Sex

Is sex good for your health and work-life balance? Here’s what these studies have shown: 

  • Sex reduces stress
    • Those who had penile-vaginal intercourse had better stress response (less reactivity and/or lower baseline levels) than those who reported other or no sexual behaviors. (Science Direct, 2006)1
  • Less sex, more work
    • People with a worse sex life tend to take on more work to compensate for their lack of fulfillment in the bedroom.

      (Spiegel International, 2007)2

      (Archive of Sexual Behavior, 2007)4
  • Sex relieves pain
    • Sex can make you feel good in more than one way. During arousal and orgasm, the hypothalamus in the brain releases the feel-good hormone oxytocin, which can act as a natural pain reliever. 
    • This surge of oxytocin may actually help women feel less pain, especially during menstruation. (Healthline, 2016)5
    • Oxytocin in men cuts pain perception by 56.5%, according to a study from the Bulletin of Experimental Biology and Medicine.
      (Bulletin of Experimental Biology and Medicine, 1996)6

      (Science Daily, 2009)9

Sex Facts by Gender

Men and women have several unique and interesting facts about how they have sex and their genitalia:

Men

  • Men don’t think about sex every 7 seconds.
  •  
    • That would mean 8,000 thoughts in 16 waking hours!
    • The young men in the study reported thoughts of sex 19 times per day on average.
      (Healthline, 2017)10
  • The Male G-spot exists
    • The “male G-spot” is a nickname for a man’s prostate.
    • The prostate can be stimulated via his perineum (the space between the anus and scrotum) or through the anus. It’s about two inches inside and is the size of a walnut. 
    • Stimulating the G-spot permits the prostate gland to be touched, leading to an intense orgasm without touching the penis. This is also known as a “prostate massage,” which targets the male G-spot, so it inevitably feels good.
      (Medical Daily, 2016)11
  • Ejaculatory Inevitability is pretty common:
    • Most men will inevitably achieve orgasm after receiving a certain amount of stimulation.
    • 75% of men reach orgasm after two minutes or less of masturbation.
      (Medical Daily, 2016)11
  • The refractory period lasts from half an hour or more:
    • Men often need rest before achieving a second orgasm — this is known as the refractory period.
    • During the refractory period, a man doesn’t think about sex or get aroused
    • It can take anywhere from 30 minutes or longer for the body to perform sexually again. Of course, this is all contingent on age, physical fitness, and lifestyle.
      (ISSM, n.d.)12
  • The average erect penis is just 5.57 inches long.
    • The smallest average penis is 1.57 inches long, while the longest average is 10.23 inches long. (The Journal of Sexual Medicine, 2013)13
  • Oral sex makes men think their penis is bigger:
    • Oral sex increased self-reported penis sizes for men. Those who received oral sex before self-reporting their size said they had significantly larger penises than men who measured after fantasizing or those who were masturbating. (Medical Daily, 2016)11
  • There are two kinds of male penises:
    • There are two kinds of male penises — colloquially known as “growers” or “showers.”
    • 79% of men are growers, while 21% are showers.
      • Grower penises expand and get longer as they get erect. For example, if a penis was five inches before being stimulated, it could get as long as seven to eight when fully erect.
      • A shower penis looks bigger when it’s not erect. This type of penis does not increase too much after erection.
        (Men’s Health, 2015)14

Women

  • 50% to 75% of women who have an orgasm require clitoral stimulation. Most women are unable to have an orgasm through intercourse alone. (Psychology Today, 2014)15

  • Clitoral orgasms can bring about anywhere from 3 to 16 contractions and last from 10 to 30 seconds. Many women can also have multiple orgasms that can include pelvic contractions. (Psychology Today, 2014)15
  • Women frequently think about and want sex, too. 53% of women were not having sex as much as they would have liked.
    • Almost three-quarters of women wished they had sex at least three times a week. (Medical Daily, 2015)16
  • Missionary is best for women with back pain. Researchers found missionary position while using a pillow for back support was best.
    • For women who have pain touching their toes or after sitting for long periods of time, researchers recommended spooning or the doggy-style position. (Medical Daily, 2014)17

    • Of course, everyone’s first time is different, but you shouldn’t expect your first time to be like what you see in the movies.
    • Sex scenes in film and television don’t happen in one take — actors often have to reposition themselves, and directors may reshoot certain parts so that the scene looks good on camera.
