The ``sex disparity'' that creates a large disparity in the number of people who have experienced sex is spreading



Some say they have never had sex before, while others say they have had sex with multiple people. When we conducted a survey on 'How many people have you had a physical relationship with?' It is clear that it is becoming more and more sexually active with many people.

Sexual loneliness: A neglected public health problem?

In a paper published in the Journal of the American Medical Association (JAMA) in 2020, during the three years from 2000 to 2002 and the three years from 2016 to 2018, men and women aged 18 to 24 Have you ever had sexual intercourse with someone?” (experienced number of people) is being investigated. According to a survey, it seems that the percentage of men who answered ``I have never had sexual activity in the past year'' in the three years from 2016 to 2018 is increasing.

Another study asked adults between the ages of 18 and 44 about their sexual activity and number of sexual partners. According to this survey, the top 20% of American heterosexuals answered that the number of experienced people will be '12', and the top 5% revealed that the number of experienced people will be '38'.

Based on the results of these two surveys, ``we can see that the number of heterosexual men in the United States has been greatly distorted,'' points out Jonah Renesen of Aarhus University, Denmark.



Renesen used the

Gini coefficient , an index that measures income inequality in society, to investigate the bias in the number of men and women who have experienced life over the course of their lives. It is clear.

South Africa, one of the most unequal countries in the world, has a Gini coefficient of 0.63 as of 2014, and Namibia, where there is also a large economic disparity between people, has a Gini coefficient of 0.59 as of 2015. . In addition, the closer the Gini coefficient is to 0, the smaller the income inequality, and the closer it is to 1, the greater the inequality.

On the other hand, when Mr. Renesen investigated the sexual disparity using the Gini coefficient, it became clear that the Gini coefficient for single men was ``0.60'' and the Gini coefficient for single women was ``0.58''. rice field. In other words, both men and women are increasingly polarized into 'sexually rich people' who experience a lot of sexual activity and 'sexually poor people' who do not experience anything at all.



Past research has shown that an active sex life has a positive impact on human mentality, so many people experience negative emotional effects due to sexual disparities, Renesen points out. In addition, he points out that more men and women who cannot experience sexual activity have fewer opportunities to develop self-esteem and positive feelings, and that sexual loneliness can cause anger and aggression. In addition, sex offenders, serial killers, terrorists, and mass murderers are often reported to have sexual frustration.

Renesen points out that the sexual disparity is widening not only in the United States, but also in many countries where young men's sexual loneliness is increasing. There is also a survey report that the number of men who have trouble finding partners in Finland has doubled between 1992 and 2015. On the other hand, the ``proportion of men who want sexual activity'' itself seems to be on the rise , and modern society is seeking ways to solve these problems.

One way to relieve sexual loneliness, Mr. Renesen said, is an 'online dating app' that allows you to date people you like online. On the other hand, he points out that matching apps like Tinder are ``visually influenced, and being rejected is particularly hurtful,'' and ``failure increases sadness and anxiety.'' .
