What does your guy's face look like during and what kind of sounds does he make?

Like most girls I can make a bit of noise in bed, not the silly over-the-top star kinda shrieking (which is ridiculous!) but the nice moans, but my bf also makes some noise when he gets really excited he kind of whimpers and gasps and he closes his eyes really tight, I find it totally hot and it's nice he's enjoying himself but I thought it was just girls who were the ones that made noise. Just wondering what other's opinions and experiences on this were.
