Lots of people find it psychologically difficult to be naked in front of other people. It can be embarrassing, maybe even humiliating. Most of us experience being naked in front of other people at sports centre/swimming pool/gym locker rooms or during medical appointments, but those are situations where nudity is expected and very much the norm. In the former, it’s common for other people to be naked too which can make it much easier to cope with.
Getting completely naked in a situation where no-one would usually expect to be naked and/or where you are the only one naked and everybody else stays fully clothed can be much more embarrassing and harder to do.
Of course, there are many people out there who are not in the least bit shy, or outright enjoy being seen naked by others, but the majority still struggle with embarrassment and shyness. There are also people out there who get a thrill from the embarrassment.
In this photo, Demi has just experienced letting her friend Sarah strip her completely naked. I think it’s safe to say she found this embarrassing. Sarah seems to be enjoying it though!
