I'm just curious to know why there are a lot of straight guys that are bothered to see other guys penises. I'm talking about scenarios where they are with friends or other guys and nudity is expected or at least is not sexual at all (roommates, changing clothes situation, locker rooms, communal showers.) I'm asking because in my experience, a lot of straight friends (coworkers, etc) talk about how they don't like to see another guy dicks even friends, and try to avoid at any cost. Is it because they're uncomfortable with nudity in general or is just that they think that looking at a penis or being in the same room with another guy naked (in a not sexual scenario) it may be a little bit gay?
