Great idea! If there was a chastity belt (for No Masturbation) and a ball gag (for Enforced Silence), then you'd have options.
On a related note, I was pretty surprised when I was poking through the code and noticed that the Pet Suit and Pet Behavior did different, though similar, effects. I can see argument on both sides of that, though, and since Pet Behavior doesn't gate anything like No Masturbation does, it doesn't seem unreasonable.
