I do so love the nihilist who quotes literary luminaries in support of his (I think) assertion that life is inherently meaningless. Do go on. Please tell us how you reached your exalted state of consciousness. But in the meantime, there was, somewhere back there, a LW with a concern you chose to ignore in lieu of climbing on the absolute relativist box.
The defenses of pornography as a stimulant have some merit, but apparently not in the personal value system of the LW, who feels guilty and really can't stomach what he is doing. Strangely, ironically, perhaps inadvertently, nieciedo is correct in applying the relativist brush. But the interesting thing (unmentioned) to the LW is that his value system can't fly with his behavior, be it relative or not. You have to ride your bike, man, and if you can't feel good about your life based on what you're doing, then stop doing those things. It's not trigonometry, after all.
