Why do people have sex?

There are various reasons why people may decide to have sex. Various studies suggest different motives behind sex. Research suggest four main motives that contain various sub-motives. These are: 1.Physical reasons, such as stress reduction, pleasure, physical desirability, and experience seeking; 2. Goal attainment reasons, such as attaining resources, enhancing social status, and getting revenge; 3. Emotional reasons, such as escalating the level of commitment and expressing love; 4. Insecurity reasons, such as boosting self-esteem, feelings of duty/pressure, and mate guarding. Of course, we don't know whether these reasons are generally relevant because cross-cultural variances in motivations for having sex are a separate study issue, but it is clear that there are several motivations and undeniable individual differences behind having sex. One thing is certain: human sexuality is fueled by a complex and varied psyche that provides a wealth of study opportunities.
