Golden formula: "having sex" 11 times a month = 1 happy woman. Not only women but men should also follow this formula to have a happy family.
In 2009, a psychology study was conducted and found that the number 11 appeared frequently on the results of happy couples.
The researchers tried to piece together data and images and interviews, but they still couldn't explain why the number 11 was so magical to the 400 women interviewed about their sex lives.
However, after research, they also pointed out the 3 most common conversation topics that easily kill your sexual desire. They are: money, work and children.
