Locker rooms are a great setting for pornos, but the logistics of banging in one are pretty complicated in real life. First of all, you should probably be prepared to stand: think about the selection of surfaces at your disposal. Not great. And then, there is the challenge of finding a locker room empty enough, and getting it to stay that way long enough. You might be an exhibitionist who doesn't mind an accidental audience, but most schools or private gyms are going to mind, and laws about public behavior may apply. And finally, of course, there is the problem of rigid gender separation in most facilities. This is only a problem for straight people, of course, and it might, on the other hand, lay the groundwork for some very interesting same-gender experiences. Locker rooms might also be happy places for voyeurs, but make sure everything is fully consensual! More on getting publicly freaky here: Exhibitionism, Outdoor Sex, Quickies
