We reviewed Mary Roach's new book Bonk & colon a few weeks ago;
The wonderful combination of science and sex, in which Roach explains how scientists solve human sexuality through strange, often hilarious experiments.
We invite readers to send their questions for Mary Roach and you can read the Q & A below.
Does female orgasm have a biological purpose?
A few years ago, Elizabeth Lloyd, a biologist at Indiana University, spent a whole book answering the question called female orgasm.
She evaluated 10 theories designed to explain the evolutionary function of female orgasm and found that all of them were lacking.
Her conclusion and colon
Female Orgasm belongs to the same file as male nipples.
The male and female embryos start using the same equipment and then separate.
Male breasts have no function;
The woman left an abnormal penis.
Not all agree with her, however.
You are welcome to refer to a recent discussion in the New York Times.
I am a happy married woman.
However, I like to masturbate once in a while because I am able to bring multiple orgasms to myself.
With the "real" climax, I can have 10-15 "small.
With these, I really don't need a sexual fantasy and can give me one even if I want chocolate.
As a scientist, I was very curious about this situation.
Is this a rare situation?
How can I reach a climax just thinking about "good, happy" things?
The climax is a reflection of the autonomous nervous system triggered by a variety of pleasant stimuli and/or combinations of stimuli.
Alfred Kinsey once interviewed a woman who could reach her climax by stroking her eyebrows.
In my study, I found a case study where a woman had a orgasm every time she brushed her teeth (
Followed by a mild seizure).
Barry Komisaruk and Beverly Whipple, researchers at Rutgers University, studied more than a dozen women who can "think" about themselves to their climax.
Some use images, some use breathing techniques.
The woman I met who could do it (
She showed me her skills on a bench outside a sushi restaurant in Oakland, California)
At the weekend workshop by sex educator Anne SPER, she taught herself with images and breathing techniques.
It took her two years to master the technology.
It is quite common for women to be able to enter a series of smaller "aftershocks" very easily and quickly once they reach orgasm (
Especially with the help of the vibrator. )
This is not only the climax obtained through masturbation, but also the climax obtained through sexual intercourse.
However, as far as I can tell, it is a rare and enjoyable gift to do this just by thinking about chocolate!
When and why is the human transition from a standard mammal estrus cycle to an ongoing sexual thinking?
Does this have to do with permanent breast enlargement in women and not just breastfeeding like other mammals?
Unlike many other mammals, humans have "recessive ovulation"-that is, men cannot judge at a glance whether women ovulate.
The genital organs and sexual organs of human women do not swell like other primates, promoting their fertility-so yes, the breasts are relevant.
There is a view that this permanent swelling helps to increase the likelihood of pairing.
To make sure he spreads his seeds, the male needs to stick to it for at least 30 days.
From an evolutionary point of view, his hope was to connect with women during that time.
Does the female hymen and any other animal have an evolutionary advantage of tissue with similar functions?
Desmond Morris's theory is that since it is painful to break the hymen, then this membrane is a natural way to ensure that young women do not easily trap sexual relationships, so, waste their genetic material on a combination with some cad that is unlikely to stay to help raise children.
However, there are two problems with this concept.
First of all, not all the pain.
Studies have shown that only 30% of women report bleeding, suggesting that Hymen often do not tear, just stretch.
Second, we must assume that hyenas play the same role in horses, whales, moles, hyenas and many other mammals that own them.
It seems unlikely.
A short answer and a colon; no-
People know what their purpose is.
At what age do humans stop having sex on average?
According to Cindy Meston, a researcher at the University of Texas at Austin's Women's Psychological Physiology Laboratory, there is very little data on people over the age of 60.
Older people rarely have a partner, so it's hard to tell whether they lack desire/interest or just because they don't have a partner.
Is it possible to "spring medicine" substances contrary to spring medicine?
I 've heard that saltpetre might work, but it sounds like a wife story.
Anything that reduces testosterone.
So anything that has a negative effect on serum amine or dopamine)
Will reduce one's sexual desire.
Anal sex has always been a popular pursuit today, or has the sex industry artificially promoted the popularity of anal sex?
Is Anal sex a physical pleasure or a social/psychological pleasure?
I believe that men always like anal sex because it is a tighter squeeze.
As for the reception end, men get pleasure from it because it stimulates their prostate.
Women have only degraded prostate, so it's not a pleasure for them.
Will circumcision make it harder for men to reach orgasm?
Some people think that yes, removing part of the foreskin will remove a bunch of nerve ends and reduce sensitivity, but others say no.
This is a topic of debate.
After male ejaculation, how long does it take to replenish the testicles with semen?
Time has changed a lot.
As with the refractory period, this period will become longer as you grow older.
