Although many types of film may be directed towards the male gender, "cockflick" is typically used only in reference to films that are not heavy in emotion (but often heavy in petting) and where the story is told largely through physical action as opposed to dialogue.
(noun) (slang) (sometimes considered offensive)
Fred: You're a cockflick addict.
Barry: Dude, I know, and I rented Rocky for tonight.
Fred: Your girl is going to be so tired of your cockflickering. You have a problem.
