Studies have yielded unexpected results.
Research carried out over 40 years gave unexpected results that were published in the professional journal Social Psychological and Personality Science.
One of the research topics was the relationship between how often people had sex with how satisfied they were with the relationship, and the findings that scientists came across surprised many.
The results showed that couples who make love once a week are generally much happier than those who do it more often or less often.
Also, it turned out that sex brings more pleasure in the bond of money, that is, couples having regular sex and lower incomes are happier than richer ones who have sex less than once a week.
