spitting
sadly the chicks just about always do it during the blowjob

(
and choking...I even watch BDSM porn and I don't like choking there either
Yeah i'm with ya there. Also:
Face slapping (slapping of the ass is great both male and female, anywhere will kill ma bone)
Spitting (in anyone's mouth or anywhere else male or female)
Humiliation (of any kind, towards male or female)
Racial Slurs (also of any kind, towards anyone)
Bukkake (had to google the spelling of that and avoided the image button like the plague)
Extreme BDSM (don't get me wrong a little wrist tying is cool, its just the whole cage/hardware/mask/err well extreme dominational stuff i can't deal with. I'm too vanilla for that)
Women fucking dudes with strap-ons
Scat (and its different disgusting forms)
Fake-ness (i.e. boobs, booties or dongs....ok most times i'll still enjoy some fake boobs here an there but nothing and i mean nothing will ever beat the real things)
Blatantly fake orgasms (porn wise its hard to tell most times, then sometimes its like...oh come on..really?)
And gay porn (naturally ya know...cause i'm straight)
Can't really think of anything else at the moment. An yeah i know, i'm kind of a prude. Ah well. Thats why amature porn win's out hands do....well ok not with well it rocks lol.
