I think there a reason the guys are quiet during adult entertainment - hardly anyone is watching to see the guy. The girl is the focus, they're being paid more, and the guy is very easily replaceable. More men are watching adult entertainment than women and we'd rather hear the woman moaning than the guy. POV adult entertainment has become extremely popular because all you see of the guy is his penis.
It's hard to really practice making noise, at least for me. All I can say is try to add some moans to your breathing during sex. That's what I try to do. Doesn't always happen but I have gotten better at letting out grunts and moans when I cum. That certainly makes them happier.
