I'm going to catch a lot of flak for this, but I think that the reason why a lot of people don't show their faces is because they know there is a chance that the picture could end up in the hands of their families, friends and co-workers. However, many people on this website seem to not care about this. I don't know how in the hell they can just post nude pictures of themselves with face and think it is perfectly ok, but whatever. I guess it all depends on the kind of culture you live in. I could speak my mind to an even further extent about some of the people here, but I'm not stupid...
