I prefer to react and communicate with my eyes, with hands, than with sound. I know some people like to make a lot of noise, but I would rather stroke her cheek with my fingers, or look deep into her eyes, than to make sounds. Well, of course I can't imagine having a quiet orgasm. I would not know how to communicate with sound, what I could communicate by alternating between a loving caress, a wild claw, an absorbed grip... with sound, I could express, "this feels amazing," but what moan or cry expresses, "I want you to feel amazing?"
