Grades & Sex

A study by the Centers for Disease Control and Prevention has found a link between celibacy and good grades.  Among high school students who earned mostly A’s, 32 percent had intercourse compared with 69 percent of their peers with D’s and F’s.  As for risk-taking measures like drinking alcohol or using condoms, the better students were more cautious.

Percentage of high school students who engaged in each behavior and their grades:

Ever had sex? A=32%, B=46%. C=59%, D-F=69%

Had sex before age? 13  A=3%, B=4%, C=9%, D-F=18%

Had sex with 4 or more partners? A=7%, B=13%, C=19%, D-F=31%

Currently sexually active?  A=24%, B=34%, C=43%, D-F=54%

Drank alcohol or used drugs before sex?  A=16%, B=18%, C=25%, D-F=40%

So the question is does having sex contribute to lower grades? Or do less sexually active students have more time to study?  Just thought I would ask.
