Teen Sex Doesn't Lead to Bad Grades ...so long as the young lovers are in a committed relationship By Newser Editors and Wire Services Posted Aug 15, 2010 3:56 PM CDT 17 comments Comments If they're committed, and sleeping together, they're probably doing OK in school. (©Www.CourtneyCarmody.com/) (Newser) – There's good news for parents who worry that their teens' sex lives will hurt their changes of getting into Harvard: A provocative new study released today has found that teens in committed relationships do no better or worse in school than those who don't have sex. The same isn't true for teens who "hook up." Researchers found that those who have casual flings get lower grades and have more school-related problems compared with those who abstain. Teens in serious relationships may find social and emotional support in their sex partners, reducing their anxiety and stress levels in life and in school, say researchers. But the study found that those who hook-up are at a greater risk of being suspended or expelled, and had lower odds of expecting to go to college. One sociologist said the results may indicate that we should revamp sex education to "emphasize the importance of relationships and spell out the consequences of casual sex." Last year, nearly half of high school students reported having sex.
