Montreal remained one of my most favorite places to play and blow off steam despite the fact that I moved to the other side of the world and have much closer and cheaper options. One of the reasons for this was confidence in the general level of sex ed and confidence that bbfs was not rampant in the Mtl scene. I've been to parts of the world where women think taking a shower after sex means you won't get pregnant. I'd never touch anyone there because the overall culture facilitates the spread of STDs. HIV is the chief concern, but as Hanna mentioned a lax culture will require things like CBJ to become the norm again because no one wants that super strain of gonorrhea.
