Is it normal music gets me off? specifically deftones.

I actually sometimes have trouble getting off without listening to music... I'm a metal/altrock kind of guy and I find Chino Moreno's vocals particularly alluring and arousing... i'm a guy, and i'm bi, but much more into girls as I don't date men as a general rule (I have to find a guy thats very attractive to me personally to conisder him attractive in general if that makes sense) It's not at all unusual for me to listen to music during sex (or masturbation although thats not something i'm partial to doing often) and in the past (don't currently have a sexual partner) i've listened to Deftones or Nine Inch Nails during either of those... i've been told i'm better in bed when listening to music, and while I know making love to music isn't at all uncommon its now come to the point where music is a crucial factor in me getting my rocks off at all... I actually get more slow and methodic when listening to Deftones and more ferocious/vicious when listening to NIN and i've come to realize that the music itself IS getting me off. Is this unusual? Am I the only one with a fetish for particular bands or a particular genre?
