While named as a “how-to”, How to Have Sex is less of an instruction manual, and more of a collection of summer break moments presented as is. At the start, when Tara, Em, and Skye run to the freezing ocean water, the film seemed like it would have all the nostalgic coming-of-age moments that they would remember forever. But as the film progresses, and the girls meet other teenagers at the resort, there’s an eerie, foreboding feel that starts to build up, with every beer bottle, with every whisper, and with every insinuation Tara receives. And rather than preach about consent, writer-director Molly Manning Walker makes them fumble around without the concept of it, the same way teens tend to do, making it much more potent than a cautionary tale.
