I must say, any chick I've been with has given tons of positive feedback (you can see it in their eyes) if I make a natural groan or any other animal-like sound...the reason they love us, is because we are animals, so embrace your animal instincts!
On a similar note, if ever I need to get a girl wet on the spot, I slide up behind her, and make a subtle but deep growl in their ear...has yet to fail.
