Haha! This has put a smile on my face
Unfortunately I know what you mean, I used to be embarrassed and try to hold it in... Ouch! Now I'm loud n proud - Except if I'm at work, not sure my staff would appreciate it. So I usually do my body magic for the week running back and forth to the loo to 'relax'
I don't know if it calms down or whether you just get used to how to control and when to let rip
