Jesus Christ. Holy Caspar konks out if you drink coffee or say "darn it" too disrespectfully to your mother. He's fucking useless. (Just ran out of my place again. Now I'm gonna start watching more porn, dammit.)
Any omni-god (omniscient, omnipotent, omnipresent) not only has to watch porn, he also has to be the porn stars.
If said god doesn't "know" what it feels like to be a porn star engaging in porn star sex, then that would be something he doesn't know and would therefore not be omniscient. Therefore god is every porn star.
If said god isn't everywhere, including in the bodies of the porn stars (specifically in the sexy parts), then that would be somewhere god isn't and would therefore not be omnipresent. Therefore god is in every porn star.
Remember the "movie in heaven" at the "last judgment?"
It's supposed to be where all the sins anyone ever committed will be revealed and shown to everyone. In other words it will be a HUGE porn movie. In fact it will contain every porn movie ever made, every centerfold photography session, all the details behind all the tabloid headlines--EVERYTHING!
If God is omniscient and omnipresent, he also can be omni-benevolent like Christians claim.
According to Matthew 5:28, just THINKING about having sex with a woman is the same as committing adultery.
Therefore, if God doesn't know what lust feels like, he isn't omniscient but if he DOES know what lust feels, then he isn't all good since he has committed the sin specified in Matt 5:28.
So not only does God have to watch all the porn in the world, he has to burn in hell for it too. Or rather, Jesus has to suffer for God watching it.
