Boston University is teaching students about safe sex and sexual health with a little bit of help from none other than wizard extraordinaire Harry Potter. Last week, as part of “Frisky February,” a monthlong series of sexual health-related events at the university, students were invited to participate in “Sex-Ed at Hogwarts,” an interactive, “Harry Potter”-themed class about safe sex, consent and sexual health. “At this event, half-bloods, house-elves, and muggles alike will learn the proper way to get consent to enter one's chamber of secrets and how to snog without getting hogwarts,” said the event’s Facebook page.
