We investigated the association between sexy-selfie prevalence and income inequality. […] Among 5,567 US cities and 1,622 US counties, areas with relatively more sexy selfies were more economically unequal. […] We investigated and confirmed that economically unequal (but not gender-oppressive) areas in the United States also had greater aggregate sales in goods and services related to female physical appearance enhancement (beauty salons and women’s clothing).

“Selfies” (self-taken photos) are a common self-presentation strategy on social media. This study experimentally tested whether taking and posting selfies, with and without photo-retouching, elicits changes to mood and body image among young women. […] Women who took and posted selfies to social media reported feeling more anxious, less confident, and less physically attractive afterwards compared to those in the control group. Harmful effects of selfies were found even when participants could retake and retouch their selfies.

When young children during their early development for the first time get their head around the fact that the reflection in the mirror is them, they are struck with a terrifying realization: All at once it dawns on them that this is how they present themselves to the world – and that the world might be repulsed by the sight. Animals, it seems, are not able to make that discovery. […] Hearing a recording of one’s own voice for the first time produces a similarly uncanny sensation.

The familiarity of the phrase ‘much ado about nothing’ belies its complexity. In Shakespeare’s day ‘nothing’ was pronounced the same as ‘noting’, and the play contains numerous punning references to ‘noting’, both in the sense of observation and in the sense of ‘notes’ or messages. […]

‘Nothing’ was Elizabethan slang for the vagina (a vacancy, ‘no-thing’ or ‘O thing’). Virginity — a state of potentiality rather than actuality — is also much discussed in the play, and it is these twin absences — the vagina and virginity — that lead, in plot terms, to the ‘much ado’ of the title.

This study utilized a sample population of married individuals specifically seeking extramarital sexual encounters (n = 1070) and investigated those factors which influence the individual’s overall perception of life satisfaction before, during, and after their affairs. Findings indicate that while affairs do tend to make respondents happy, a number of factors influence perception of life satisfaction during an affair, including a belief that an outside partner is required to remain in a primary partnership, a desire to remain in the primary partnership, at least biweekly sexual events with the outside partner, a belief that the individual loves their outside partner, and seeking out the partnership due to sexual dissatisfaction within the primary partnership. There was also a gender effect. A surprising finding was that even after the outside partnership ends, respondents reported a higher life satisfaction rating than before the outside partnership.

Postcoital Dysphoria (PCD) is a counter-intuitive phenomenon characterized by inexplicable feelings of tearfulness, sadness, or irritability following otherwise satisfactory consensual sexual activity. Prevalence of PCD has been reported among females, but not among males. […]

The present study utilized an anonymous online questionnaire to examine the prevalence and correlates of PCD amongst an international sample including 1,208 male participants. Forty one percent reported experiencing PCD in their lifetime and 20% reported experiencing PCD in the previous four weeks. Between 3-4% of the sample reported experiencing PCD on a regular basis.

Women differ greatly from one another in terms of their tendency and capacity to experience orgasms. The improvements in gender equality and sexual education since the 1970s have not helped women to become more orgasmic. Neither has the major increase in masturbation habits (among women in general).

One challenge for future studies is to understand why women value their partner’s orgasms more than their own.

Long-term relationships and especially marriage have long got a bad rap in terms of the erotic. The German poet Gottfried Benn, for example, stated: “Marriage is an institution for the paralysis of the sexual instinct” Even women like the American author Erica Jong join in the lament. “Even if you loved your husband, there came that inevitable year when fucking him turned as bland as Velveeta cheese: filling, fattening even, but no thrill to the taste buds, no bittersweet edge, no danger.” That such remarks are not far-fetched, psychologist Kirsten von Sydow from the University of Hamburg has verified with a comprehensive literature review. […]

This loss of libido in marriage is also called the “Coolidge effect”. Among cattle breeders, it is known as the bull’s reluctance to mount the same cow repeatedly, with the libido returning after the encounter with a new cow. The name Coolidge refers to the 30 U.S. President Calvin Coolidge (1872-1933). According to a famous anecdote, Mr. Coolidge once visited a farm with his wife where Mrs. Coolidge became aware of a cock who just mounted a hen. When they told her that the cock accomplished this feat up to twelve times a day, she replied: “Tell that to my husband!” When the president learned of the miracles, he asked: “Always with the same hen?” When he was assured that it was another one every time, he replied: “Tell that to my wife!” […]

The Coolidge effect can be expressed in numerical values, says von Sydow. “In the first year of living together, the weekly coital activity of three times drops to just under twice, then it further diminishes over two to three years.” […] For gay and lesbian couples, the decline in coital frequency is at least as strong. And this is not a question of age, because after a divorce and with a new partner, the sex drive is easily rekindled. […]

“Men love the idea of getting between the blankets with a woman just for fun, including with a woman with whom they do not want to have a long-term relationship,” Baumeister points out. “From the standpoint of these men, sex affords pleasure, and sex with new partners affords a particularly great pleasure. Why shouldn’t they have it off other with those women without tying up? Unfortunately for these men, most women do not share that view. ”

We explored the effect of revealing or conservative attire on perceptions of women’s leadership competence. We also used eye-tracker technology to determine whether looking at sexualized body parts (i.e., breasts, hemline) was related to lower perceptions of leadership competence and electability.

A female candidate for a student senate presidency at a U.S. university wearing revealing clothing was perceived by 191 college students as less honest and trustworthy, electable, and competent than one wearing conservative clothing. Sexualized body parts were looked at longer when the candidate was wearing revealing clothing compared to conservative clothing. Furthermore, mediation analyses indicated that the revealing clothing led participants to gaze at sexualized body parts, which, in turn, led to perceiving the candidate as less honest/trustworthy, which lowered their evaluations of her competence and electability.

These findings suggest that viewing a woman in a sexy outfit can lead others to stare more at her body and make negative evaluations of her personal attributes.

Why the Victorian era saw a surge in female births and war begets boys

There is empirical evidence that heavy sexual activity increases the chances that conception will occur before the most fertile time of the female cycle, as the woman may be pregnant by then. And the data also suggest that, possibly for hormonal reasons, such conceptions are slightly more likely to be boys. “It doesn’t take much imagination to suppose that the ends of wars, with servicemen home on leave or returning home, are associated with fairly intense sex – more babies were born in the UK in 1919 than any other year in history. Put all these together and you get the conclusion – frantic fornication breeds boys.”

[…]

Which brings us back to the mysterious surge of female births in the late Victorian period. Could it be that, in the same vein in which heavy sexual activity increases the sex ratio, a  trend towards sexual inactivity lowers it? “Victorian morality” distinguished itself through a set of values that espoused sexual restraint, with an increased condemnation of masturbation and sexual activity in general, repressing any form of sexuality other than penetrative intercourse. And indeed, statistics reflect a steady decline of sexual activity throughout the Victorian period, reaching its lowest point in the year 1898. But as there was less sex going on, conception tended to occur around the most fertile time of the months, bestowing a (relative) excess of baby girls on the Victorians.

Hypothesis 1

Up to circa two decades age, it was generally supposed – but without hard supporting evidence – that pregnant women exposed to adverse environmental circumstances were at increased risk of foetal loss, and that male foetuses were at greater risk than female foetuses; and that therefore the liveborn infants produced by stressed women contained a higher proportion of daughters. That hard evidence has now been accumulated in a series of papers by Catalano and colleagues, and others.

Using time-series analysis, it has been shown that the Sex ratios at birth (SRB) briefly declined, slightly but significantly, some three to five months after many catastrophic and other adverse events e.g. the terrorist attacks on September 11th, 2001; the Troubles in Northern Ireland (1969–1998), the Breivik shooting in 2011 in Norway, the Sandy Hook shooting in 2012 in Connecticut; the assassination of President Kennedy [though the effect in this case was more marked in non-White than White births]. […]

Thus there is overwhelming evidence that sex ratios at birth are partially controlled by maternal stress-induced selective culling of frail males in utero, resulting in a conception cohort with a low sex ratio at birth. It has also been postulated that the ratio may be skewed because of fertilization of non-optimally matured oocytes under these circumstances. Moreover, it has also been hypothesized that higher coital rates will lead to ejaculation of newly formed spermatozoa cells, possibly leading to a preponderance of Y-sperm since it is also hypothesized that X-sperm age faster and are eliminated earlier.

However, it will be appreciated that selective culling of frail males during pregnancy cannot explain some of the established variations of SRB. First, it cannot explain why some reported sex ratios are higher than prevailing norms. Second, it cannot explain why these norms almost always exceed 0.5 (equal numbers of males and females).

Hypothesis 2

It has been hypothesized that human sex ratios at birth are partially controlled by the parental hormone levels of both parents around the time of conception. Ex hypothesi, high levels of testosterone (in either parent) and/or of oestrogen (in the mother), are associated with subsequent male births. And high levels of gonadotrophins (in either parent) are associated with subsequent female births. Most of this evidence is observational and correlational, and is in accordance with the hypothesis of Trivers & Willard.

Some clients even become a “human ATM,” meaning they give her complete control over a bank account. […] Last year she made over $1 million in cryptocurrency alone.
