Whatever gets you into your groove, man. I'm normally a fan of Static-X. Slipknot, Megadeth, Korn, Powerman 5000, stuff like that. I can't listen to that kinda stuff when I'm doin' the do, though. Too aggressive, sex turns into some wierd kind of angry attack/meting-out-punishment kind of thing. Which is cool every once in a while, but not on a regular basis. I normally go for something a little lighter but still rockin' during sex, something like Saliva or - hell, I don't know - Pink Floyd usually works pretty well for me.
