After 20 years and nearly 20 clients a day, there is no reason for you to be uncomfortable removing your undergarments in front of me.  I have seen every size, shape and color lady parts on the planet. Whatever you're sporting down below cannot surprise me or scare me.  Rest assured, my only agenda is to make you soft as a baby's bottom in a safe and comical environment.
Cheers to A Happy Hoo-Ha!
