Gokkun and Bukkake are, I think, the closest thing to "creative art" that exists in porn. I don't find either even remotely erotic personally but I respect the image of a woman kneeling and covered in male ejaculate. The complete removal of anything even appearing remotely to be related to sexual gratification for her is what ensures, to me at least, that it's not porn...it's a depiction of the real value of the whore at the center of the screen. She's not worth anything more than to be a cum target. THAT is art. Not erotic, but art nonetheless.

So simple answer....quit trying to jack off to this kind of stuff.
