Maybe… (emphasis mine):

. RESULTS: Controlling for age, physical maturity, and mother’s education, a significant curvilinear relationship between intelligence and coital status was demonstrated; adolescents at the upper and lower ends of the intelligence distribution were less likely to have sex. Higher intelligence was also associated with postponement of the initiation of the full range of partnered sexual activities. An expanded model incorporating a variety of control and mediator variables was tested to identify mechanisms by which the relationship operates. CONCLUSIONS: Higher intelligence operates as a protective factor against early sexual activity during adolescence, and lower intelligence, to a point, is a risk factor. More systematic investigation of the implications of individual differences in cognitive abilities for sexual activities and of the processes that underlie those activities is warranted.

U.S. National Library of Medicine National Institutes of Health: Smart teens don’t have sex (or kiss much either)

I must be missing something because it looks to me like both higher and lower IQ teens were less likely to have sex. So doesn’t that mean being average is a risk factor?
