Did you encounter anything embarrassing when you wiped your back in the bathroom?

Once I took a bath in the bathroom with my colleagues, and then my colleagues hired a back cleaner. When rubbing his back, his skin was too slippery, and then when rubbing, I rubbed it into the water and poked off a piece of skin. He was injured at that time, too. Alas, why does it feel wrong? We all laughed at that time.
