Mathematicians prove that `` men are difficult to reach orgasm if they are too excited in the early stages of sex '', and what is the excitement level at which men perform best?

A mathematician at the University of Sussex in the UK has announced that 'it turns out that men who are having sex are less likely to orgasm when they feel excessive psychological excitement.' Research data that observed sexual intercourse of hundreds of men and women and data that scanned the brains of people during sex were analyzed with a mathematical model.

Getting too excited can stop men from orgasming – but there's a solution

“Sex as depicted in movies, music, and other popular culture may give men the impression that it is a simple phenomenon, at least physically. It requires collaboration,” caution applied mathematicians Konstantin Blyuss (right) and Yuliya Kyrychko (left) at the University of Sussex.

According to Blyuss et al., about one in five British men suffers from erectile dysfunction, and that proportion reaches 50% in their 40s to 70s. In response to this report, the two decided to mathematically model men's sexual responses and explore ways to improve the problem.

Blyuss et al. focused on two major research data, focusing on sex with formulas. One of them is a 1966 paper summarizing data collected from 10,000 sexual acts.

American researchers William Masters and Virgina Johnson, who wrote this paper, invited more than 380 women and more than 300 men to the lab and closely observed how the participants engaged in sexual activity. From the results, Masters et al. discovered that the human sexual response follows the cycle of ``excitement'', ``plateau (stagnation)'', ``orgasm'', and ``dissolution'', as well as physiological changes in the reproductive organs at each stage and an increase in breathing. , increased pulse and blood pressure, and unconscious sweating immediately after orgasm.

This research was groundbreaking at the time, but it was later found that unlike men, women do not follow a linear course of 'excitement', 'plateau', 'orgasm' and 'elimination'. It has also been criticized for not taking into consideration psychological factors, and only capturing physical reactions.

Therefore, Blyuss and colleagues combined the data from Masters et al.'s study with data from five studies that used functional magnetic resonance imaging (fMRI) to scan the brains of people during sex to determine the physiological characteristics of men during sexual activity. We modeled changes in both data and psychological arousal.

Below is part of the mathematical model they described in their paper.

The study found that too high an initial level of psychological arousal before or during sex impairs a man's chances of reaching orgasm. One reason for this is that being overly aroused causes you to focus too much on your sexual performance and achieving orgasm.

Getting too excited and preoccupied with reaching orgasm can lead to anxiety, which in turn leads to a 'psychological hyperstimulation state.' As a result, it is said that it will fall into a frustrating situation that it is likely to climax but it can not climax.

To avoid this, you need to lower your psychological arousal by turning off your mental switch and relaxing. Mr. Blyuss commented on this, 'In short, our discovery is'don't think too much'.'

In addition, in the mathematical model constructed this time, it was also found that ``physical excitement decreases due to psychological stimulation''. This seems counterintuitive, but it is consistent with fMRI research data that many areas of the brain are inactivated just before orgasm.

From this, Blyuss et al. 'In other words, it can be said that orgasm is related to liberation.It is both physical and mental liberation.'

For certain tasks, not just sex, an 'intermediate level of psychological arousal' leads to optimal physical performance. Established as the ' Yerkees-Dodson Law, ' this law states that, for example, difficult or inquisitive tasks require a low level of arousal to increase concentration, requiring stamina and endurance. These tasks require a high level of excitement to keep you motivated.

The current study focused on men and does not apply to women who have more varied sexual responses, including having one or more orgasms. Also, there are gender differences in orgasm between men and women, such as about 95% of men experience orgasm, while only 65% of women experience it.

The next step for Blyuss and Kyrychko, who have mathematically elucidated the male orgasm, is to elucidate the female orgasm using the latest 'Basson's circular model,' which models the female sexual response. It is to develop a mathematical model and eliminate the orgasm gap between men and women.
