76 Orgasm Statistics

By Bedbible Research Center / March 28, 2023

This is a meta-analysis of the phenomenon that is orgasms. The study looks at all available orgasm statistics and combines the results to provide the most accurate statistics on age-old questions surrounding male and female orgasm.

orgasm statistics from vaginal sex show that only 1 in 5 women orgasm from vaginal sex while 19 in 20 men orgasm during intercourse

Some of the questions you will likely find answers to include but are not limited to: How many women orgasm from intercourse? Is there an orgasm gap (based on orgasm frequency and time to orgasm) between men and women? And if so, how big is this? How many have never orgasmed before? How likely are different sexual orientations to orgasm during intercourse?

For access to the full dataset or questions regarding the findings presented in this article, please reach out to researchcenter@bedbible.com

Key orgasm statistics

  • Only 12.9% of women report consistently reaching orgasm through penetration alone, while 18.4% of women can reach orgasm in this way.
  • 81.6% of women / females can’t orgasm from penetration/intercourse alone.
  • 65% of heterosexual women report they usually experience orgasm during intercourse, while 95% of men usually orgasm.
  • Men on average take 5 minutes to climax during partnered sex, while women on average take 14 minutes (while only 8 minutes during masturbation)
  • 59% of women have faked an orgasm.
  • Women report that 51-60% of the time they have intercourse they climax (orgasm) only if they are simultaneously stimulated externally.
  • 25% of women report that they almost always reach orgasm during intercourse.

Orgasm frequency

  1. 64% of women report that they orgasmed in their last sexual encounter.
  2. 91% of men report that they orgasmed in their last sexual encounter.
  3. 18.4% of women say that intercourse without any external stimulation is sufficient for them to orgasm.
  4. 25% of women report almost always reaching orgasm during intercourse.
  5. 95.1% of men report that they almost always reach orgasm during intercourse.
  6. 51% (to 60%) of women report that they can easily orgasm during vaginal sex if they simultaneously get clitoris stimulation.

The Orgasm gap between men and women

  1. Men are 42% more likely to have reached orgasm during their last sexual encounter compared to women.
  2. Men are 280% more likely to report that they almost always orgasm during intercourse compared to women.
  3. Women are twice as likely to have faked an orgasm compared to men.

Have never had an orgasm

  1. 8.5% of women have never had an orgasm (5-12%, depending on the survey).
  2. 92% of women who never had an orgasm before manage to reach orgasm after clinical treatment.
  3. 12% of women aged 17-28 years old report that they have never had an orgasm at any point.
  4. It is estimated that 4% of all women go through life getting an orgasm.
  5. 30% of women report that they “rarely or never” orgasm during vaginal intercourse.

Sexual orientation – homo-, hetero- and bisexual

During our meta-analysis we looked at how the data showed differences depending on the sexual orientation of both respondents or study participants.

What we found was quite interesting:

  1. 95% of heterosexual men orgasmed during their last sexual encounter.
  2. 65% of heterosexual women orgasmed during their last sexual encounter.
  3. 89% of homosexual men orgasmed during their last sexual encounter.
  4. 86% of homosexual women orgasmed during their last sexual encounter.
  5. 88% of bisexual men orgasmed during their last sexual encounter.
  6. 66% of bisexual women orgasmed during their last sexual encounter.

By looking into comparing these different groups we find that:

  1. Heterosexual men are 42% more likely to orgasm compared to heterosexual women (95% vs. 65% for heterosexual women).
  2. Homosexual women are almost as likely as homosexual men to orgasm (86% vs. 89% for homosexual men).
  3. Heterosexual females are the least likely group to orgasm compared to both men of all sexual orientations as well as compared to both bisexual and homosexual women.
  4. Bisexuality is the sexual orientation amongst men with the lowest chance of reaching orgasm of all other sexual orientations.
  5. Homosexual women are 32% more likely to orgasm compared to heterosexual women (86% vs 65% for heterosexual women, and 66% for bisexual women).
  6. Sexual orientation is a bigger pre-determinant of orgasm frequency amongst women compared to men.

We also look at asexuality, and found that:

  1. Asexuality is not predetermining sexuality for never having reached an orgasm. 77% of asexual women report that they have climaxed before.

Relationships status – the effects over time on orgasms

While looking at the metadata for how different types of relationships and the time they lasted affected the rate of orgasm during intercourse the results were significant. Especially when isolating by gender.

  1. Only 11% of women orgasm during their first-time hookup with a new partner.
  2. 16% of women have experienced an orgasm during the first or second hookup with a new partner.
  3. 34% of women report getting orgasms with partners they have had more than 3 hookups with prior.
  4. 67% of women in relationships (>6 months) report experiencing orgasms.
  5. Women that have been in a relationship for more than half a year are x6 more likely to get an orgasm during sex compared to first-time hookups.
  6. Hooking up for the 3rd, 4th, and 5th time improved the odds of reaching an orgasm for women by 40% compared to the first and second hook-ups with a new partner.
  7. Hooking up more than six times makes it twice as likely that the woman will reach orgasm compared to the first hookup.

What you do in bed matters for if you reach an orgasm

In the below table, we found the following likelihoods of certain sexual practices to improve the chances of reaching orgasm during sexual intercourse.

  1. If you stimulated yourself, you are 2.2 to 2.3 times more likely to reach an orgasm during both hookups and in relationships.
  2. If your partner stimulated you, you are 2.3 times more likely during hookups to orgasm (while only 2 times more likely in relationships).
  3. Stimulating your partner with your hands increases the odds of reaching an orgasm by 1.6 too 1.8 times.
  4. Receiving oral sex has a lower chance of getting you to orgasm (1.9 times more likely) compared to if you stimulated yourself with your hands (2.2 times), or if your partner stimulated you with their hands (2.3 times).
  5. Performing oral sex only increases the chance of reaching orgasm if you are in a relationship.
  6. Anal sex does not increase the chance of reaching orgasm in hookups, while it does improve the chance of orgasms by 1.6 times in relationships.
  7. In relationships, receiving oral sex has the biggest effect on the chance of reaching orgasm (by 2.9 times), while it is hand stimulation in hookups that increases the chance of reaching orgasms the most (2.3 times more likely).

(2020). Orgasm-induced seizures Definitions
• Orgasm-induced seizures is a rare neurologic disease characterized by complex partial seizures with or without secondary generalization, or idiopathic primarily generalized epilepsy, triggered by sexual orgasm.

• Seizures usually start immediately, shortly after or a few hours after the achievement of orgasm, last a few seconds or minutes, and are followed, in very rare cases, by intense migraine.

• The exact cause of orgasm-induced seizures is unknown, but it is thought to be related to the release of neurotransmitters during orgasm.
 
V. Puppo (2013). Anatomy and physiology of the clitoris, vestibular bulbs, and labia minora with a review of the female orgasm and the prevention of female sexual dysfunction Clinical anatomy• The clitoris is the homologue of the male’s glans and corpora cavernosa, and erection is reached in three phases: latent, turgid, and rigid.

• The vestibular bulbs cause “vaginal” orgasmic contractions, through the rhythmic contraction of the bulbocavernosus muscles.

• Orgasm is an intense sensation of pleasure achieved by stimulation of erogenous zones, and women do not have a refractory period after each orgasm and can, therefore, experience multiple orgasms.		100

A. Vesey (2014). Orgasmology by Annamarie Jagose (review)
• Annamarie Jagose argues that there has been a lack of theorization of the orgasm within queer theory due to a dismissal of its importance.

• Jagose believes that the orgasm is an irregular and unpredictable formation that should be critically recuperated to better understand its place in queer theory.

• Jagose applies her titular neologism throughout in a nod to the queer practice of wordplay and in defiance of the ways in which her own research was undermined by the Australian mainstream press.
 
Sam Mcbean (2016). Orgasmology by Annamarie Jagose (review)
• Annamarie Jagose’s Orgasmology is an insightful mapping of the fields of sexuality studies and queer theory, while also creatively opening up new entry points into theorizing sex.

• Orgasm is an “unruly scholarly object” that straddles the cultural, the biological, and the textual, making it an attractive object for Jagose and a thrilling read for readers.

• Jagose uses orgasm to explore heteronormativity’s “timing”, the “double bind of modern sex”, and to think “queerly” about sex and sexuality.
