According to survey by Trojan and The Sex Information and Education Council of Canada released on Tuesday, a quarter of Canadian university students have never had vaginal, oral, or anal sex. Of the 72% surveyed who had had sex in the past year, only 51% said they used a condom, despite the fact that 34% described their last encounter as casual.

Given that the rates of gonorrhea and chlamydia have increased dramatically over the past decade, especially among young people, the findings, surprising or not, are unnerving.
