For me anyway:
1) Bad boob jobs
2) Obese or anorexic looking performers
3) Scat
4) Spit swapping, gagging, and/or puking
5) Excessive male vs female violence (face slapping, choking, etc)
6) Old people in porn (I mean really old)
7) Bukkake and gangbangs (although I'd love to see reverse gangbangs, where large groups of women have their way with 1 guy)
