Getting it on for science - best electric toothbrush 2016

Mary Roach is a cool scientific writer who is not shy of playing guinea pigs in the lab, even if it means convincing her husband to take part in a "sexual intercourse" study while a doctor stands, wave an ultrasound stick to the couple.
Roch, a former Salon columnist, is known for her amazing humor and respect in her 2003 best-selling book, stiff: Curious Life of human corpses.
"After her death, she went straight to science to try to fight the afterlife in spook.
"For her recent adventures in Weird Science, she ventured back to the place where bunker: strange coupling of science and sex.
Roach found that for centuries doctors have reached some extremes in order to improve the sex life of patients.
But first, they have to try to figure out exactly what's going on during sex, which is harder than it sounds.
"Bonk" is more like a vaginal surgery than a cleavage surgery.
There are very few cheap thrills here, but Roach finds a lot of things fascinating ---and laugh at --
From prescription-
A powerful vibrator for surgical testicle implants for sterilization of dogs.
(Hint: this is really to make the owner of the dog feel better.
) She traveled to Taiwan, London, Denmark, Egypt and other places to witness the penis implantation operation, and also watched pig farmers artificial insemination for sows along the way.
However, the field action of observing heat in the field of sexual research may be more difficult than achieving multiple orgasms without foreplay.
The privacy of the subject of study needs to be considered, and in addition, many studies on human sexuality are now conducted through a behavioral questionnaire rather than in a laboratory.
Finally, sometimes Roach had to use a vaginal photo detector, or of course her husband, Ed, to observe under a microscope in person.
The most pleasant thing about "Bonk" is not just the strange things it reveals about the history of sexual beliefs ---
If the two testicles are good, the three testicles are good! --
However, little is known about some of the basic mechanisms of human sexuality.
Sharon and rocky talked about sexual science in our San Francisco office.
Leonardo da Vinci, the earliest sex researcher, drew many amazing physiological diagrams from the body.
He is interested in what happens when people have sex.
He just tried to imagine it and then drew the number.
These details--
Unfortunately, it's not accurate. -drawings.
I like to think of him as the original. Fast-
Forwarded millions of years to Robert Dickinson, the amazing guy who made the Golden race start.
Kinsey has been working on gall.
Formation of wasp species-
No sex on radar. -
He met Dickinson.
Robert Dickinson, a gynecologist in Late 1800 and early 1900, began interviewing patients for sex.
First he started asking them questions and then he asked them to actually show how they masturbated.
It was a bit shocking at the time.
You will think, "Oh, he must be some kind of abnormal with ulterior motives," but he is not at all.
Dickinson felt very strongly that bad sex was a waste of many marriages.
He let people in and they thought the outer labia and penis should go as far.
They thought they were having sex and didn't know why they weren't pregnant.
Even today, will the idea that research people are a bit abnormal continue? Oh, yes.
The woman, Cindy Meston, who has a lab at the University of Texas at Austin, said: "If someone on the plane says 'OK, what did you do,' I wouldn't say, 'I am a sex researcher.
Because they inevitably think you're a pervert, or you have to really dig.
However, one wouldn't think if you were a Geneticist: "Oh, you have to really dig the genes!
Sex researchers always think so. -
Big eyebrows.
How this attitude around sex researchers and research affects their funding will certainly make it harder for them, especially in the Internet age, as conservative groups can now go to these government databases
Funded research, Insert keywords such as "sex" or "penis" and then get a list of unethical studies from these researchers
"So how do researchers solve this problem using a vague term.
So you say "physiological" reactions, not "sex ".
Research tends to draw money to where, and for the past 10 years, people have been trying to find a "female Viagra" since Viagra came out ".
"Obviously you can't just use Viagra. They tried.
Believe me, they tried it.
It doesn't work at all. What happens is that it does lead to an increase in the amount of genital blood, but does not reach the point where women really notice it.
If you do a physiological measurement: Yes, there is a difference, but when you ask a question, the woman says, "Well, I don't notice anything.
"So it doesn't matter.
On paper, this is a significant difference, but not in their lives.
Sex researchers measure that there may be differences between what happens to the genitals and how women feel when sex researchers do a female awakening study, and they tend to use explicit fragments ---porn.
A researcher found that women say they prefer women. centered porn.
In other words, men focus on the sexual needs of women, not just sex.
The woman would say, "it makes me more excited.
I hate the stag deer movie.
It has no effect on me.
"But if you look at their blood volume, they respond the same way to both of them.
So it's more subtle for women.
Didn't you find a study that shows that women also react to gay male porn and bon chimpanzees?
This is something completely unexpected.
There is really no difference in the woman's reaction to herself, which is completely counter-intuitive.
It doesn't matter who makes love in the video, women have physiological reactions.
This does not mean that they tend to have sex with bon chimpanzees, just causing them to [be] inconsistent with their own sexual tendencies, unlike men.
The straight man was opened by the straight man.
Lesbian sex also excites them, but they see two naked women.
Women also seem to be more distracted when making love.
In one of his books, Kinsey said: "cheese crumbs scattered in front of a pair of mated mice distract the female mice, but do not distract the male mice.
"The attempt to improve the female sexual experience has a distorted history.
For example, the Princess's clit was moved.
Can you talk about the princess? Why is she doing this? grand-
Napoleon Bonaparte's niece had the idea that the distance between the vagina and the clit would determine how a woman was awakened during sexual intercourse.
She was very upset because she had never reached an orgasm during sexual intercourse.
By the way, her husband is gay;
I don't know if this works at all.
She was unable to reach her climax during missionary posture sexual intercourse.
She decided to have something to do with the clit instead of trying a different location
Vaginal distance.
She did a lot of measurements on women and then asked them "did you orgasm during sexual intercourse" and found a correlation between the distance between the clit and the vagina.
In other words, during sexual intercourse, the clit is not stimulated at all, in some of the women who are far away.
She, like herself, called those "téléclitoridiennes "---
"She came from the distant clit.
"During the operation, she worked with the French doctor, who first tried on the body and then tried on her twice.
Sadly, it doesn't work for the first or second time.
She is a tragedy in the history of sexual surgery.
In the pursuit of better sex, men have not been immune to strange surgery.
Why ever thought that if two testicles were good, maybe the third one would make things better for the Ottoman Empire, there was a Pasha with 80 wives, noticed by the family obstetrician, every morning, pasha is drinking this sake made of hoof testicles, just like goats and sheep.
The doctor thought, "Hey, the testicles seem to be the source of strength, because this guy has 80 wives and he has children all the time, so there must be something in the broth.
"Then, the doctor began experimenting with the animal, inserting a section of one animal's testicles into the testicles of the other animal, and then thinking that they looked stronger.
It's basically like a transplant, so the immune system will close it up with such a hard lump inside.
It's about what they got from the whole thing, a hard little lump.
But, surprisingly, it caught.
At the age of 1920, the testicles were a big deal.
There's a guy, doctor.
Brinkley, who has this radio station in the Midwest, will broadcast, "a man is only as big as his glands!
"People will go to his factory by train, and they can pick the sheep themselves and put a part of the testicles in their testicles.
The placebo effect has a long way to go.
I believe a lot of people are happy with the operation of the testicles.
Today, about 25 men had erection problems and Viagra couldn't help.
At the Center for Research on microscopic surgical capacity reconstruction in Taiwan, what surgical treatments do they have, there is a doctor who does the technique, and he ties up some veins of blood from the penis.
In other words, if you get less outlet from erection, it will stay longer.
The problem with it is that the body will re-discharge blood over time.
If you block a path, the body will re-grow the veins, so after year 45, people's satisfaction usually starts to drop.
Maybe this doctor in Taiwan is really, really good at it.
But in the United States, people who have studied it have found that this is not long --term fix.
How today's researchers research in the laboratory. The advantages of the current ongoing physiological study are related to women's sexual desire and awakening.
This device, called vaginal photography, was studied.
It looks like an acrylic tampon that is connected to a cable that curls out from between your legs and is sent to the computer.
In fact, all it measures is how much capillary blood activity is there, which is a way to measure awakening.
It's a drug test.
They will, when measuring a female porn segment, before taking the drug, and then after taking the drug, show the female porn segment and then compare it.
There is also a subjective measure.
This is also very important for women to ensure subjective improvement.
So, the researcher came up with something called arousometer that looked like an automatic shift device on the car.
As a woman watching porn, she will move the small indicator up and down according to her excitement.
Researchers will then have subjective and physiological markers of how they are awakened in a sexual situation.
Is it hard for them to get people to do these studies? Most of these people are undergraduates who are getting some course credits or cash to answer your questions, no, they are not in trouble.
College students can easily be tempted to do something to make money quickly.
But it's more challenging for couples to study in the lab, and it's also very, very rare.
Since Masters and Johnson, there have been very few physiological studies of couples, because you don't need to do that to some extent.
When you research, you are either studying to wake up. -
Part of the sexual cycle-or orgasm.
So the easiest way is to let someone in to masturbate.
If couples make love in the lab, more because they have problems, they go to sex agents or therapists and they ask for help for their own situation.
You can hardly see it except Ed and me in Dr.
Deng Ultrasound Research.
From time to time, something pink appears.
What's going on, doctor?
Deng has this new technology.
Two-dimensional ultrasound film.
He was just trying this technique and he mentioned in one of his papers that he had a plan and that he wanted to shoot sex, which I think is the term he used.
I wrote him a note saying, "Can I come whenever you have a couple to do this ? " Then he wrote back and said, "it's hard for me to find a brave couple to do it, so let me know if your organization knows someone.
So my organization, Mary Roach.
I thought about it and I let the poor man do it.
From my point of view, it's like a strange, slightly awkward medical procedure.
First of all, I am taking notes.
Talk about distractions! Exactly. Dr.
Deng held his wand, as you did in the fetal ultrasound, right on my stomach, so it was impossible to be awakened.
It's like when your gynecologist says, "Now, you'll feel my fingers in gloves in your rectum.
"You're like," Okay.
"It's normal in a surreal way.
While this may be rare, someone has sex on an MRI machine, right, yes.
In 1991, Jupp and Ida were the first to have sex on an MRI machine.
By doing so, what do you know, who are these people? There was a Dutch biographer, Pek van Andel, who was inspired by Leonardo, a direct perspective of two people having sex.
He brought in two of his friends, Jupp and Ida, who agreed to do so.
They're acrobats.
They are in good health.
This is a very small space.
They were the first to succeed.
In previous attempts, the person was unable to maintain an erection because you had to stay still for a minute.
They couldn't do the research until Viagra invented it.
They put it on hold.
They just gave up for a while, and then Viagra came--
A researcher called it a "godsend "---
Then they could do it, and then they scanned a group of people.
In the end, they learned that the roots of the penis are much longer than anyone realizes. It's two-
Third, the length of the part you see, which is a bit interesting, but to be honest, I think it's more important --
Let's see what we found.
When Viagra was discovered, how Viagra changed sex research, it took off in such a huge way, and suddenly the holy grail became, "Let's find something else for the other 50% people on Earth.
"So, people are crazy about finding" female Viagra ", just putting in a lot of money, because whoever wins the prize will make a profit in a fantasy way.
All of a sudden, women and their sexual response are the focus of attention.
Now, female sexual dysfunction is divided into sexual dysfunction or "sexual loss ".
"Hypo" is like "Hypo" in low ".
It just means low sex, which means you don't think about sex and you're not particularly driven to have sex.
Then there is a separate wake up barrier category where you may be very excited, but the thrill doesn't help you at all.
This is very rare.
Then there is the climax barrier.
Previously doctors used vibrators to treat women with "hysteria" but you found that the vibrators are still on now.
There is a device called the Eros clit treatment device.
Basically, there is a small suction cup at the end of it.
But it's mainly because it has a motor.
Its vibration is the same as that of an electric toothbrush, which, by the way, is used as a vibrator-
Or they used.
The device will attract more blood to the clit, but so will masturbation.
I called people and I said, "Okay, so what's the difference between this $400 device and a vibrator, or just your own finger," they would say, "I really don't know.
This is a good question!
"Cindy Meston said that she is a woman in Texas who has a female Psychological Physiology Laboratory, in order to add a layer of legitimacy to a device, otherwise someone may use or even prescribe uncomfortable.
The doctor can say, "Well, there's this device.
This is an FDA-approved product to increase women's awakening.
Why don't you give it a try "and then they feel like they have a medical solution to a medical problem.
Doctor's order!
You think science has completely solved some of the problems about human sexuality, and it turns out that what exactly triggers ejaculation and what physically determines the functioning of the male body, "Okay, let her tear!
"They don't know exactly what triggered it. Orgasm as well.
This is a reflex of the autonomous nervous system, but it can be triggered by people from the stimulation of the clit to the stroke of the eyebrows.
Some people have spontaneous orgasms, which makes them very embarrassed.
In Saudi Arabia, there is a woman who suddenly has 13 spontaneous orgasms.
Epilepsy can sometimes cause epilepsy.
This is certainly far from simple and clear.
There are many mysteries outside.
