Generally I tend to be pretty quiet, but when I do make a noise I tend to be a growler. However, when I'm in the mood to talk dirty, I can really let rip. However, I've gotta say that despite my own tendencies, I love a really noisy partner, one who'll moan, scream, yell and talk dirty to me all the way through will really get me going, and probably get me responding in the same vein.

Classical conditioning has a lot to answer for, I think.
