Variety is the key. It depends on the mood. If I'm relaxed, and there's some slow sexy music playing as I slide in and out in the heat, a nice quiet moan, mixed in with the heavy breathing can be a real turn on. At other times, when I get rock hard, I just want to thrust hard and deep and fast. Harder and faster and far more energetic. That's best when accompanied by louder noises of sex, grunting and swearing and screaming. Raw animal energy.
Just tell him he's missing out on a massive part of the enjoyment of sex. Feeling a woman bucking around under your tongue, panting and moaning is one of the most rewarding parts of sex. If you want to feel like a man, make her feel like a woman. The incredible closeness and sexiness of using your tongue on a woman and watching her reactions is amazing. I think that men who don't 'get it' are missing out. Sure, it can be am acquired taste, like many of the very finest things in life.
I sometimes shave the shaft, down to the base. I love the feel of it when I slide it into my missis when freshly shaved. I can feel the wetness of her lips. She doesn't like it though - she prefers a man's cock to be hairy and natural.
