No , I don ' t know who that is . <| sep |> It ' s not really about not squishing genitals . The genitals are fairly adept at avoiding being squished . It ' s the way a mans hips and legs fall when relaxed . The angle of the hips in a man angle slightly more outward , which means keeping your legs parallel requires conscious and active effort , unlike women who ' s hips tend to have the thighs parallel at rest . No , it ' s not a lot of effort to keep your legs together but it can turn into a decent amount of effort if sustained for a long period of time . It ' s like sticking your arm out to the side 90 degrees to your torso . No it ' s not difficult to do . But try to do it for an entire half hour train ride . It ' s really fucking uncomfortable .
