Everything about this is troubling. The fixation on pornography, the reduction of any given erotic stimulus to the instantiation of a sex act, the mechanization and rationalization of sexuality at every level. Absolutely pathological.
Humans are a walking pile of barely coherent pathological behaviors, and even that is sometimes such a stretch, that in a hypothetical scenario where a star faring, faster than light alien intelligence is observing us, I'm deeply ashamed for humanity. If anything, there is not enough fixation on pornography, instead of too much fixation.
