It's a no-brainer that the female orgasm is still a mystery to many men. (Should we provide them with a map to the clitoris, perhaps?) But it's not a stretch to say that many women could also use more education when it comes to reaching climax, whether solo or with a partner.

After all, orgasms may not be biologically necessary; unlike men, women can conceive a baby without one. But they are pretty damn important when it comes to a healthy sex life. And as with most areas of sexual health, the more info you have, the more empowered you are to get what you want—and need—when it comes to crazy pleasure. With this in mind, read up on these 10 mind-blowing facts about what's happening when you're getting your mind blown in bed.

Okay, so no one's even actually counted. But doctors estimate that between 6,000 and 8,000 nerve endings exist in the clitoris, says Lauren Streicher, MD, associate clinical professor of obstetrics and gynecology at Northwestern University and author of Sex Rx . "What you see is just the tip of the iceberg," says Dr. Streicher. "[The clitoris is] basically a horseshoe kind of configuration around the upper part of the vaginal opening."

Considering how many nerves this pleasure spot has, it makes sense that women are way more likely to orgasm from clitoral stimulation. One recent study published in the Journal of Sex & Marital Therapy found that only 18% of women orgasm from penetration alone. "That number may be as low as 10%, or at best 25% to 30%," says Dr. Streicher. "The bottom line is that the majority of women do not have an orgasm from penetration and need clitoral stimulation."

A study of 800 female college graduates found that approximately 43% reported having had multiple orgasms. So exactly what is a multiple orgasm? "Some women experience long, cascading orgasms, where you continue to have strong rhythmic pelvic contractions for a long time," says Dr. Streicher. "And then there are orgasms where you have that over-satisfied sensation which stops and then, with more stimulation, starts again."

But if you're a one-and-done kind of women, don't stress about it. "There are plenty of women who, after they have one nice big orgasm, feel a real sense of fulfillment and satisfaction and they're done. And that's totally normal," says Dr. Streicher.

There's really no right amount of time for your orgasm to last. In fact, researchers used to think that 3 to 15 seconds was about the duration of a female orgasm. Then they found evidence that a climax could go on for 20 seconds to 2 minutes. The journal Ceskoslovenska Psychiatrie published data showing that 40% of women estimated the duration of their orgasm to be 30 to 60 seconds or even longer, and 48% of women experienced predominantly long orgasms.

The takeaway: "Some people have very short orgasms, while others can last longer," says Dr. Streicher. "There's a wide variety of normal."

It's kind of a stereotype, but there's science behind it. Way back in the 1960s, sex researchers William H. Masters and Virginia E. Johnson (the inspiration for Showtime's Masters of Sex ) found that it took women about 10 to 20 minutes of sex play to reach orgasm, compared to just four minutes for men. "There's a wide range," says Dr. Streicher. "We know that this has to do with how aroused someone is advance, and how intense the stimulation is."

Why women tend to need more arousal and varying types of stimulation isn't clear. But it's a good argument for finding a sex-positive partner who won't rush things and will make sure you cross that finish line when your brain and body are ready.

Suffer from headaches? Try getting it on. Sixty percent of migraine sufferers experienced moderate or complete relief after an orgasm, according to research published by the International Headache Society.

But there are headaches that are actually caused by orgasms. "The first is bothersome but not dangerous—it's just a general headache-y feeling that people can get during sexual activity," says Dr. Streicher. "But then there's the person who, at the exact same time that they have an orgasm, will have a very painful explosive headache simultaneous with orgasm."

If that's the case, you want to get to your doctor ASAP. She says that this kind of pain has a high correlation to subarachnoid hemorrhage, a type of stroke caused by a burst blood vessel in the brain. Yikes.

Feel like you can't think straight when you have an orgasm? You're not exactly wrong. "An orgasm mediates other neurotransmitters that impact other functions," says Dr. Streicher. In fact, research at the University of Groningen in the Netherlands showed that orgasms deactivate the area in your brain that processes fear, as well as the parts that regulate your "vigilance for danger."

They also found that your self-control and "moral reasoning" decreases in the moment of that big O. "When scientists do active MRIs during orgasm, they can see where there's heightened activity and where there's decreased activity—that's certainly very real," says Dr. Streicher.

In the same way having an orgasm changes your brain, it can also crank up your pain tolerance. In one study , women's pain threshold during orgasm increased by 75%, and their pain detection threshold increased by 107%. Not surprisingly, this tolerance to pain has to do with feel-good endorphins and oxytocin (a bonding hormone) that are released when you orgasm. The effect will last about 10 to 20 minutes. On the other hand, men's brains don't release oxytocin when they orgasm. They experience a boost in pleasure, yet they don't reap the pain-killing benefits.

Your DNA could be responsible for at least a third—and maybe even 60%—of your ability to reach the big O, according to research published in the journal Biology Letters . It's not exactly the kind of topic you want to bring up with mom, so it's hard to determine exactly what role DNA plays. But it could be anatomical, says Dr. Streicher.

"If you look at the ability to orgasm during intercourse, we know that it correlates with the distance between the clitoris and the urethra: If your clitoris is less than 2.5 centimeters from the urethra, it's more likely that you will orgasm during intercourse. And that's simply because of clitoral stimulation based on anatomy."

Recent research puts the number of women who experience female ejaculation at around 54%. But that same research found that up to 66% of women experience coital incontinence, or excreting urine at orgasm. And it's hard to tell the difference between ejaculate and urine, says Dr. Streicher.

"With female ejaculation, what we're generally talking about is an emission of fluid from the Skene's glands, which are little glands on the side of the urethra," she explains. "Some women do lose urine when they orgasm, but it's very diluted so it doesn't smell like urine. So it's not so obvious what's happening."

Either way, it's just what your body does. "One of the questions that comes up all the time with my patients is whether there's a way to make it stop," says Dr. Streicher. "If it's ejaculate, no. If it's urine, there are opportunities to try and decrease or eliminate incontinence. But I get a surprising number of women who tell me they want to ejaculate. How can they make that happen? I have no idea."

Let's look at the stats. Ninety-five percent of heterosexual men reported that they usually or always orgasm during a sexual encounter, while only 65% of heterosexual women said the same thing, according to a recent study published in Archives of Sexual Behavior.

"You have to keep in mind the biological purpose of sex: to reproduce. A female orgasm is not required in order to conceive," says Dr. Streicher. "But I always say the reason the clitoris is located where it is so that women can self-stimulate during intercourse to orgasm."

Interesting, women in same-sex relationships are more likely to orgasm: 86% said they usually or always reached climax when sexually intimate. "The reason why is kind of obvious," says Dr. Streicher. "They're not depending on intercourse to reproduce, and certainly a woman in a same-sex relationship is far more likely to know where her partner's clitoris is and what to do with it than most men. That's just the reality."

Vaginal contractions during orgasm "suck" the sperm higher into her reproductive system. This feeling is why blowjobs are so popular to men. It feels so similar.
Women have orgasms for the same purpose men do. To create an interest in sex and for better chances of reproduction. Raping women is not exactly what nature intended. An average man is stronger than an average women because men are supposed to protect women, while women sustain the population by giving birth. Sexual pleasures and orgasms exist in order to motivate animals to take part in reproduction. Female orgasms are in fact, more important than male orgasms. They help in the internal movement of female reproductive systems to lodge the sperm in correct position in a much efficient way.

It could have been the other way around. Male orgasms could have been very painful and the sperm would still come out. Refraining from sex for males is already painful. Women have a much better self control but almost equal sexual desire.
There’s a type of spider where males die after they have sex. So, there males have sex only once throughout their whole life and they die young. Nature might have done that to humans too. What’s the harm ? Humans would still survive and the poisonous patriarchy would have been absent. Even better.
I have a better question, why do males exist anyway ? Men are totally useless. They exist just to create trouble and make lives difficult for women. The less males the better. Nature should have created a mono-gendered female human species. No more disgusting males like you. No more patriarchy.

A new study examines "orgasmability" to determine whether it serves a purpose or is just an evolutionary accident

There may be few questions of human sexuality more rancorous than those about the female orgasm. Scientists agree that women probably started having orgasms as a by-product of men having them, similar to how men have nipples because women have them. As Elisabeth Lloyd, a philosopher of science and theoretical biologist at Indiana University put it in her 2005 book The Case of the Female Orgasm: Bias in the Science of Evolution: “Females get the erectile and nervous tissue necessary for orgasm in virtue of the strong, ongoing selective pressure on males for the sperm delivery system of male orgasm and ejaculation.” But why we ladies still have orgasms is hotly debated.
Male orgasms exist, it’s widely believed, to encourage men to spread their seed. On face value, it would be easy to say that women orgasm for the same reason: to encourage them to have sex and make babies. But in practice, compared to male orgasm, female orgasm is very difficult to achieve. There’s a lot of variation even within individual women, and 10 percent of women never have them at all. And, unlike male orgasm, female orgasm isn’t a prerequisite for pregnancy.
So why do women have orgasms at all? There are two firmly opposed camps on this question. The first group proposes that it has an adaptive function in one of three categories: pair bonding, mate selection and enhanced fertility. I’ll break these down. The pair-bonding theory suggests that female orgasm bonds partners, ensuring two parents for the offspring, while mate selection offers that women use orgasm as a sort of litmus test for “quality” partners. The enhanced fertility theory, meanwhile, proposes that uterine contractions during female orgasm help to “suck up” sperm into the uterus.
The by-product camp, on the other hand, claims that female orgasms are to this day an incidental by-product of male orgasm, not an evolutionary adaption. “There’s no documented connection between women who have orgasm at all, or faster, having more or better offspring,” Lloyd says.
The schism between the two camps deepened this month with the publication of a new study of twins and siblings in Animal Behavior that seems to rule out the by-product theory of female orgasm. Researchers Brendan Zietsch at the University of Queensland in Australia and Pekka Santtila at Abo Akedemi University in Finland asked 10,000 Finnish female and male twins and siblings to report on their “orgasmability” (their word, not mine). They looked for similarities in orgasm function between female and male twins. If the by-product theory of female orgasm is true, they say, this similarity should exist. Due to the inherent differences in orgasm between women and men, females were asked to report how often they had orgasms during sex and how difficult they were to achieve, while males were asked how long it took them to reach orgasm during the act and how often they felt they ejaculated too quickly or too slowly.
Zietsch and Santtila found strong orgasmability correlations among same-sex identical twins, and weaker yet still significant similarities between same-sex non-identical twins and siblings. However, they found zero correlation in orgasm function between opposite-sex twins. “We show that while male and female orgasmic function are influenced by genes, there is no cross-sex correlation in orgasmic function — women’s orgasmability doesn’t correlate with their brother’s orgasmability,” explains Zietsch. “As such, there is no path by which selection on male orgasm can be transferred to female orgasm, in which case the by-product theory cannot work.”
Zietsch says he doesn’t have a favorite theory on the evolutionary function of female orgasm, but if forced to guess he’d say that it provides women extra reward for engaging in sex, thus increasing frequency of intercourse and, in turn, fertility. (There’s no proof of this yet, though, as Lloyd points out.) Zietsch continues: “I’ve shown in another paper, though, that there is only a very weak association between women’s orgasm rate and their libido, so the selection pressure on female orgasm is probably weak — this might explain why many women rarely or never have orgasms during sex.”
Lloyd and other proponents of the by-product theory agree that weak selection pressure could be acting on female orgasm, but not enough to maintain it over the eons of human evolution. Rather, if female orgasm bestows any reproductive benefits onto the human race, it would be by happy accident. Unsurprisingly, Lloyd has a lot of bones to pick with the recent study. Comparing different orgasm traits in women and men is a textbook case of apples and oranges, she says.
Kim Wallen, a behavioral neuroendocrinologist at Emory University and frequent collaborator with Lloyd, explains it thus: “Imagine that I wanted to compare height in men and women. In women I used a measurement from the top of the head to the bottom of the foot. In men I used how rapidly they could stand up. Would I be surprised that each measure was correlated in identical twins within sexes, but uncorrelated in mixed-sex twins? Such a result would be what was predicted and completely unsurprising. Zietsch and Santtila have done the equivalent of this experiment using orgasm instead of height.”
Wallen also points out that previous research has shown that traits under strong selective pressure show little variability, while those under weak pressure tend to show more variability. With human orgasm this bears out in that men report almost always achieving orgasm during sex, while the ability to orgasm during intercourse varies widely among women. (Penis and vagina size – both necessary for reproduction — show little variability, suggesting they are under strong selective pressure, Lloyd says, while clitoral length is highly variable.) Wallen asserts that Zietsch and Santtila, “chose to compare apples to oranges because the evidence is so strong that men’s and women’s orgasms are under different degrees of selective pressure, the very point they were trying to disprove.” Yikes.
To their credit, Zietsch and Santilla acknowledged the limitations of their study, both in the paper and in Zietsch’s email to me. More work obviously needs to be done. “Figuring out the function of female orgasm, if any, will probably require very large genetically informative samples, fertility data, and detailed information on sexual behaviour, orgasm rate, and the conditions and partners involved,” Zietsch says. “I do have plans, but the debate probably won’t be settled quite some time to come.”
If, at this point, you’re as frustrated as me, you might be wondering what we do know about female orgasm. Well, we’re closer to knowing why they’re so few and far between during sex. In a paper published online this January in Hormones and Behavior , Lloyd and Wallen found that the farther away the clitoris is from the urinary opening, the less likely it is that the woman will regularly achieve orgasm with intercourse.
