I'm the type of person who doesn't let anyone touch my stomach for many reasons. Besides my boyfriend. I was at the store and the cashier an older lady asked me if I was having a boy or girl and I answered. She then tried to touch my stomach which I obviously moved because I don't let my own family's touch my stomach let alone a stranger. Is this just me or anyone else feel the same way?
