By chastity checks, I assume we are really talking about checks of the chastity devices in use?
My partner checks both my self (for hygiene and abrasions etc.) daily and my devices (CB and thigh bands) for hygiene and damage. She makes sure that all locks are operating properly so that in an emergency I could use my keys to free myself. I suppose she doesn't check the locks for scratches or damage but then, since I wear my devices voluntarily, there really isn't any need. 😂
