Here's my increasingly addled attempt to compile what we've decided so far:

#1: whores lie
#2: male performers have NO stroke value
#3: way too much man-ass in hetero porn (please minimize the use of the dreaded "ball-cam" angle. Any amount of time that 70% of the screen is occupied by the dude's ass and nut sack is too much)
#4: double-pen in the same orifice is gay
#5: Generally, European porn stars are much dirtier than their American counterparts
#6: when a dude is getting it up the ass, no matter if it's from a woman, tranny or another dude, it's gay
#7: if you have a small dick and fuck like a chick with a strap on you shouldn't be a stunt cock
#8: interracial gangbangs demonstrate how far we’ve come as a country regarding race
#9: if she doesn’t do anal, and she’s not Christy Canyon, she’s not a legitimate porn star
#10: piss, vomit and/or scat ain't sex(y)
#11: too many tattoos and piercings and it becomes an unpleasant freak show
#12: if you must show cunnilingus, make sure the guy doesn’t have a moustache (see Ron Jeremey and Christy Canyon; looks like the Tribbles Star Trek episode)
#13: the male talent shall keep grunting and moaning to a minimum
#14: don't jump to the guy's face during the money shot
#15: there shall be no unattended pussy in a FFM threesome scene at any time
#16: close up shots have their place, but it's not two thirds of the movie; pull back, establish and let us get on with the important business of jerking off to the whole girl, not just the meat piston
#17: genuine sounds of balls slapping against girl's ass or cock slamming into wet cunt shall not be interrupted by talents' over dramatic moaning or porn banter
#18: The bts interviewer shall not ask how the girl got into porn if she's been doing porn longer than 6 months
#19: if it's a comp, let the box cover say it's a comp; don't dress it up as all new scenes
#20: if the movie is shot in HD, cast must have good complexions (and definitely, no ass zits)
#21: if it's on the box, it shall be in the movie
#22: if an act is described as “her first time”, it shall not be common knowledge that it is far from her first time
#23: unless your name is Andrew Blake, let us hear the actual noises instead of the music, no matter how much you paid your cousin to create it with Pro Tools
#24: squirt is pee (see #10)
#25: every whore has a price
#26: the more cum that lands above her mouth, and the more surprised/upset she is about it, the better; if she actually starts to whimper, it's rewind time
#27: in porn, for every one great boob job, there are 76 shit ones around the corner
#28: someone else’s baby jam on/in a girl is off limits; stick your dick elsewhere or towel her off/make her swallow before proceeding
