Hardcore. Definitely films showing internal cum shots with the cum oozing out. Young pretty women getting fucked by older, (can be overweight), unattractive men. Gang-bangs. Orgies. Double Penetration. Triple Penetration (a.k.a. "Air-tight"). Fisting. Women getting fucked by guys with HUGE cocks.

I prefer seeing the hardcore because there isn't a lot of "warm up" time and much dialogue. Hardcore gets straight to the nasty sex. Which is how I write....
