There are so many elements to this. I know people who are totally at ease being naked in front of other people but hate being the centre of attention. For them being the only one naked is only embarrassing because of the attention it draws.
Other people are totally humiliated by being naked in front of other people but love the attention (or indeed the humiliation itself!).
There’s also the element of bravery. You can be brave enough to overcome your shyness.
