Those who have promiscuous and casual sex lives are at greater risk of depression. Experts found higher levels of general anxiety, social anxiety and depression among college students who had recently had intercourse with a stranger or with someone they had met days before the act. 3,900 heterosexual students took part in the study. 11% of them, most of them men, reported that they had frequent casual sexual partners in the past month. The volunteers reported increased anxiety and depression as a result of their promiscuous sex lives, said study leader Dr. Melina Bersamin of California State University. The results of the study indicate that students who have casual sexual contacts have a negative impact on well-being and the situation related to psychological stress.

The results and data from the study are published in The Journal of Sex Research. Previous studies have shown that women react more negatively to casual sex than men. The reason, according to specialists, can to some extent be sought in the double standards that allow men to have more sexual partners than women.
