A new study from the Canadian Women's Foundation found that while almost all Canadians agree that sexual activity between partners should be consensual, two-thirds do not understand what consent means. If you can't tell if someone is consenting, ask: "Are you okay with this?" Encourage them to answer honestly. Decent people treat others with respect, especially when it comes to something as intimate as sexual activity. Sexual activity without consent is sexual assault. It's all pretty simple.
