I've noticed that porn without sound doesn't do much for me... I NEED to have audio to get real turned on by porn. In fact, I'd prefer audio without visuals to visuals without audio.
But, I don't like porn with background music. It totally ruins it for me... all I want to hear is the panting and moaning and whatever other sounds the bodies involved make, not music. I especially like to hear men moaning in ecstasy... such a turn on.
How does everyone else feel about this? What sounds turn you on, what doesn't turn you on?
