I love moaning ... or squeaking/screaming/grunting.... the stranger the better. Let me hear you enjoying yourself in the strangest way possible. If you give me sounds that might embarrass yourself in any other situation then I know you're in the moment.
Silence can be a killer.
There are well established theories on sounds that transfer emotional arousal. In movies, marketing and in-person communication the excitation-transfer theory purports that arousal in one situation generates arousal in another. (

So ladies, give me your best primal passion booster .... a purrrr, grunt, moan, scream, squeak, yell my name or your favorite religious quote, whisper that you are loving the experience.... what ever it may be make it 10 times bolder than you actually are.
After all, sex is a primal act... give it your dirtiest primal response!
