Aren't people who are underwear models shy?

Shyness is certain. After all, the female model is an adult, and the underwear he makes you wear is uncertain. The size of underwear is very troublesome, is it leaking? Wearing hot underwear is very troublesome, and you have to do all kinds of strange postures. Underwear is so big, it may reveal something if you move it. You only wear so little clothes. If there are many people on the set, you must be embarrassed. Others may just let you get dressed. Let someone else take a video, then that person will take a picture around your underwear, then walk up to you and pull your underwear directly, and then the camera will move up to the other person's underwear. Will he still put his hand on your underwear and say what material it is? That would be awkward. If the underwear is not so small, he may pull it off your underwear, which will be very strange, but the model's annual salary is also quite large, but this process is too uncomfortable.
