Ever wonder what they did before apps? And even before chat rooms? Well, gays in the 70s were totes creative with their Hanky Code. Brian Fairbairn and Karl Eccleston are educating the younger gen, and giving mature audiences a little nostalgia, we’re sure.

Although we feel we’d be a bad host if we didn’t give you a heads up that while this four-minute trip down hanky-memory lane, starts as a fun and flirty traditional sex ed tape, it gets real graphic. Like, if you trust us, you probably don’t need to see the last minute.
