Research published in Social Psychology and Personality Science found that among college students, those who enjoyed casual sex reported higher well-being and self-esteem levels, compared with students who did not have casual sex.
Interesting. For years it was said that those who engaged in casual sex had low self-esteem and that casual sex, at best, offered a temporary boost and worsening of self-esteem in the long term.
More research may be needed. And perhaps the research should be done for all age ranges.
