How confident does a man have to be to wear a wig?

[DepressedByHairLoss]

Hey Weedwhacker, I have 3 questions about hairpieces:

1. Does wearing a hairpiece destroy the hair that should be growing underneath the glue that holds the piece onto your head?

2. If you're with a woman and getting intimate, is it easy for her to detect?

3. How easy is it for a hairpiece to get loose and slip when you're sweating while working out?
