Infidelity Lurks in Your Genes

We have long known that men have a genetic, evolutionary impulse to cheat, because that increases the odds of having more of their offspring in the world.

But now there is intriguing new research showing that some women, too, are biologically inclined to wander, although not for clear evolutionary benefits. Women who carry certain variants of the vasopressin receptor gene are much more likely to engage in “extra pair bonding,” the scientific euphemism for sexual infidelity.

I’m not surprised. My informal interviews with women indicates a bimodal distribution. Either women 50 years and older have had a relatively small number of sexual partners, less than 10 or else dozens or, sometimes, many hundreds.

Most Americans Have Tried Unconventional Sex
The popularity of unconventional sex raises questions about what’s “deviant.”

…

Imagine a playground filled with happy children. Some can’t get enough of one activity: the swings, slide, sandbox, carousel, climbing structures, whatever. Others sample two or three. Some circle among everything. And others avoid the various stations, preferring to make their own fun alone or with others. What can we say about children who love swings, but never use the slide? What does it mean if all kids do is play in the sandbox? It means nothing. It’s play, and kids play in the ways that appeal to them individually.

Sex is adult play. Like a playground, it includes myriad possibilities, none better or worse than any other. Absent harm to self and others, it doesn’t matter how adults twist the sheets. It’s play. It’s pleasure. And erotic pleasure is uniquely individual.

So we must think long and hard before labeling any legal sexual possibilities weird or deviant. There is no normal, so we must be careful calling anything abnormal.

I never would have guessed this would have happened, Hawaiians watched a lot of porn after fake incoming missile alert.

The Tweet from Pornhub:

Stress relief? If so, you might say it’s another application of Dr. Joe’s Cure for Everything.

But it could also be a decision to enjoy themselves while they can because they never know if it will be their last chance.

This might be useful in certain circumstances:

Scientists have known for more than a half-century that our pupils dilate whenever we see something we find sexually arousing. This is a non-voluntary response that is controlled by the autonomic nervous system—the body system that controls other automatic responses like heart rate, respiration, and digestion. As a result, it’s not something that people can consciously control, so it gets around the problems of people lying on surveys and faking genital responses.

For example:

a new set of studies published in the Journal of Sex Research finds that—among men—pupil dilation doesn’t just reveal the gender of the people they’re attracted to, but also their age.

…

when viewing images of children, no increase in pupil size was observed for men in any sexual orientation group. In fact, if anything, their pupils actually had a tendency to constrict when viewing kids. The results of all of these studies suggest that pupil dilation holds a lot of promise as a technique for measuring attraction based on both gender and age.

…

it could also be quite useful to forensic researchers who study pedophilia and other sexual interests that people are strongly motivated to conceal.

It’s not mind reading, but it might be close enough to make life safer for your kids in some situations.

Do you like to live dangerously?

These are the most dangerous sex positions.

They left out “in bed with a woman who has a jealous husband”.

From Justin J. Lehmiller, 5 Ways Women Can Orgasm That Don’t Involve Sexual Activity:

1. Some women can literally think themselves to orgasm.
2. Some women have orgasms in their sleep.
3. Some women have orgasms while they exercise.
4. “Nipplegasms” are a thing, too.
5. Some women have experienced orgasm during childbirth.

While I’m sometimes envious of all the sexual advantages women have I only have to remind myself that I never had and never will have the risk of going through childbirth.

Dr. Joe’s Cure for Everything may help you live longer:

Scientists have uncovered the first biological evidence that frequent bedroom activity boosts lifespan by protecting our DNA.

…

The study focused on telomeres — protective caps on the ends of DNA — that predict a person’s biological age.

Thought of as tiny internal clocks, they shorten with time and eventually become so small that cells die.

…

Shorter telomeres have been associated with aging, disease and a higher risk of death.

The researchers found women who had sex during the course of the week-long study had telomeres that were up to 30 percent longer.

But relationship quality had no effect on them.

Scientists did not study men, but believe an active love life would also add years to their lives.

I’m thinking they should add nuns, Catholic priests, monks, and prostitutes into their study populations.

In the mean time go with the best evidence to date and don’t be a science denier. If you want to have a better chance at a long and healthy life take Dr. Joe’s advice.

Scientist now know more about how Dr. Joe’s Cure For Everything helps your heart:

Sex is good for the heart because it reduces the levels of a harmful chemical in the blood, scientists believe – but the effect is only seen in men.

Having sex several times a week can cut lead to better circulation and healthier blood vessels in men, which researchers say is crucial for preventing a build-up of the chemical homocysteine.

But scientists say women benefit much less because sexual arousal is less dependent on having a healthy blood flow, which is a key factor in keeping homocysteine under control.

The study is small and I’m concerned about which is cause and which is effect but one could conclude that Dr. Joe’s Cure for Everything boosts brain power:

Having lots of sex when you get older boosts brain power, scientists have discovered, with people who have regular sexual relations scoring better on verbal, visual and spatial perception tests.

A team of researchers from the universities of Oxford and Coventry, U.K., carried out a study on 28 men and 45 women aged between 50 and 83. The participants were asked about their sex lives, including how often, on average, they had had intercourse over the last 12 months. Answers included never, monthly and weekly.

They were also asked questions about their general health and lifestyle, and undertook a test that measured their brain function. This test assessed attention, memory, fluency, language and visual and special abilities. For example, for the verbal test they were asked to name as many animals possible in 60 seconds.
