The dinosaurs had sex… and look what happened to them #abstinence


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.

Of all the criticisms aimed at fracking, charges that it might increase the incidence of STDs – specifically gonorrhea – are seldom heard.

Yet there might be a link – according to a new research paper published in the Journal of Public Health Policy. […]

We find that fracking activity is associated with a 20 per cent increase in gonorrhea.

The woman, who calls herself Theodora, is a financial dominatrix, which means clients — many of whom never meet her in person — derive sexual pleasure from giving her gifts and money. Exchanges of money can range from several dollars in “tributes,” as they are called, to gifts of more than six figures. 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.

While pornography is not the only medium in which orgasm is portrayed, it is the most explicit, and it is widespread and easily accessible. As such, pornography is an ideal medium for examining representations of male and female orgasm. […] Only 18.3% of women, compared to 78.0% of men, were shown reaching orgasm.

In the stillness of remembering what you had, and what you lost


Heterosexual men were most likely to say they usually-always orgasmed when sexually intimate (95%), followed by gay men (89%), bisexual men (88%), lesbian women (86%), bisexual women (66%), and heterosexual women (65%).

Compared to women who orgasmed less frequently, women who orgasmed more frequently were more likely to: receive more oral sex, have longer duration of last sex, be more satisfied with their relationship, ask for what they want in bed, praise their partner for something they did in bed, call/email to tease about doing something sexual, wear sexy lingerie, try new sexual positions, anal stimulation, act out fantasies, incorporate sexy talk, and express love during sex.

Women were more likely to orgasm if their last sexual encounter included deep kissing, manual genital stimulation, and/or oral sex in addition to vaginal intercourse.

As men are generally more short-term oriented in their sexuality than women, and given that cigarette and alcohol use are still considered masculine behaviors, we explored if female smoking and drinking can function as a short-term mating strategy. […]

The experiment showed that young men perceive women who use cigarettes and alcohol as being more sexually unrestricted. Furthermore, tobacco and (especially) alcohol use brought some short-term attractiveness benefits to women. In short-term mating contexts, drinking enhanced women’s attractiveness, whereas occasional smoking was found equally desirable as not smoking. However, in long-term mating contexts, frequent drinking and all smoking behavior harmed women’s desirability.

This study aims to investigate the frequency and amount of female DNA transferred to the penis and underwear of males following staged nonintimate social contact with females and to compare the findings with the amount of female DNA transferred to the penis and subsequently to the underwear of a male who had engaged in unprotected sexual intercourse with a female. […]

It was possible to demonstrate that DNA can occasionally transfer to the waistband and outside front of underwear worn by a male following staged nonintimate social contact.

Passion and sexual satisfaction typically diminish in longer-term relationships, but this decline is not inevitable. We identified the attitudes and behaviors that most strongly differentiated sexually satisfied from dissatisfied men and women who had been together for at least three years (N = 38,747). […]

The vast majority of these participants reported being satisfied with their sex lives during their first six months together (83% W; 83% M).

Satisfaction with their current sex lives was more variable, with approximately half of participants reporting overall satisfaction (55% W; 43% M) and the rest feeling neutral (18% W; 16% M) or dissatisfied (27% W; 41% M).

More than one in three respondents (38% W; 32% M) claimed their sex lives were as passionate now as in the beginning. Sexual satisfaction and maintenance of passion were higher among people who had sex most frequently, received more oral sex, had more consistent orgasms, and incorporated more variety of sexual acts, mood setting, and sexual communication.

Anyone we could marry would, of course, be a little wrong for us. It is wise to be appropriately pessimistic here. Perfection is not on the cards. Unhappiness is a constant. Nevertheless, one encounters some couples of such primal, grinding mismatch, such deep-seated incompatibility, that one has to conclude that something else is at play beyond the normal disappointments and tensions of every long-term relationship: some people simply shouldn’t be together.
