The Lighthouse (2019) is a gritty drama where two lighthouse keepers on a remote island in the 1890s lose their sanity while holed up in their small lighthouse. Robert Pattinson and Willem Dafoe are the stars who both get shirtless in different rainy, dark scenes. Willem is naked, but his strong legs hide his crotch from the camera. Robert, however, jerks off and while we don't see much, the angle is very hot. We DO see his ass. Luckily, the fog is clear for that full moon!
