Having sex while in a romantic relationship doesn't generally affect teens' grades in school, but casual sex might, a new study shows.

"Compared to abstinence, sexual intercourse in committed romantic relationships is often academically harmless, whereas in other types of relationships it is more detrimental," noted Bill McCarthy and Eric Grodsky, sociologists at the University of California, Davis and the University of Minnesota, respectively. "Females and males who have sex only with romantic partners are generally similar to abstainers on most of the education measures we examined."

Compared to abstainers, teens who only have casual sex are at greater risk for lower grades and problems in school, and are more likely to be expelled or suspended, less likely to be attached to school, and less likely to go to college.

The study was to be presented Sunday at the American Sociological Association's annual meeting in Atlanta.
