When was your first sexual experience? Recently, a survey published in the American "Health" magazine showed that having sex for the first time too early or too late may affect future marriages.

This study targeted 1,500 American teenagers and tracked their love experiences and future marriages from the ages of 15 to 30. The results found that those who had sexual experience before the age of 18 and those who experienced their "first time" after the age of 30 may have more marital problems in the future, such as being prone to cheating and not being able to handle the relationship between husband and wife. And those who had their "first time" around the age of 23 were better able to deal with problems in their marriages and communicated more smoothly with their partners.

Researchers believe that having sexual experience too early and being physically and mentally immature may lead to wrong concepts of relationships and thus affect marriage. And having sexual experience too late means less contact with the opposite sex, so communication problems are more likely to occur.
