How to moan 
Know that moaning is involuntary, in theory. 
A moan is a noise of passion that escapes you when you're overcome by pleasure or sensation-usually in a sensual context. It's a way of vocalizing how good you're feeling.
However, not everyone is prone to " being loud, " and many people have a hard time making their sensual feelings public. With practice, confidence, and a supportive partner, you may learn to unlock your moan and make it feel more natural.
