I agree with just about everything everyone has said so far, except for Pumpin's "skanky slutbag" comment. I especially agree with everyting SirNeal8 said. I also agree with oneguy67's comment about gay porn being my norm, so straight porn seems a little bit "pervy" to me, which, of course, makes it extra thrilling.
I love "nasty" porn, if everyone involved seems to be genuinely genuinely turned on by the action. I do NOT like to see women being tricked, abused, mistreated, degraded, spit on (literally or figuratively) or any other such nonsense, even if everyone is obviously "acting." That kinds of stuff turns me off instantly and leaves me feeling sick.
Also, I don't want to see bleached blonde, breast-enhanced, bimbos with Cleopatra eye-makeup and Freggy Krueger fingernails shrieking like banshees while getting nailed by muscle-bound morons. It's artificial, contrived, unattractive, annoying, and contains absolutely nothing I can relate to.
I DO want to see natural, attractive, normal looking people enjoying real,
hot, passionate, uninhibited, nasty sex (including orgies, gangbang, creampie, DP, public sex, etc.) without guilt or shame.
