hahaha I've seen some porn where the noises the guys make are way more fucked up!
shrieking like little girls when they cum, looking (and sounding) like they've having an epileptic fit or something...
it makes me crack up laughing whenever I find one of those 'vocal' type of guys
as far as the sluts who go nuts vocally go, well there's always the mute button (or a gag if you're in RL and not just watching

)
