His desire decreased if she made more money

If a guy is married to a woman with a higher income, his sexual desire tends to decrease compared to other men.

Professor Lamar Pierce, a researcher at Washington University in the US, and colleagues studied more than 200,000 couples in the US and Denmark to find out the connection between income and sexual desire. They found that the percentage of husbands with lower incomes than their wives fell into a much larger state of sexual excitement than other men, The Star reported.

"About 10% of men with lower incomes than their wives have used sexual stimulants to fulfill their husbands' obligations , " Pierce said.

The professor commented that the salary of the wife is not the perpetrator directly causing her husband's " sex " desire to decline. The most important reason is: Wives with higher incomes often play a role in the family. That situation negatively affects men's self-esteem, causing their desire for wives to decrease.

"The sexual desire of men depends on a number of factors. The greater the role of men in the family, the higher their income and the greater the number of social friends, their sexual desire. The stronger, " Pierce explained.

Some previous studies show that men's sexual desire can reduce due to excessive drinking, stress, physical weakness, chemicals on food, sushi eating habits, some diseases. In addition, men's sexual desire can be reduced after they have children or enter the "menopause" period.
