Gleaned from this thread. Especially the following quote:
OK, so those deeply disturbing anime flicks depicting tentacled aliens violating pretty waifs in and out of every orifice, spewing spunky protoplasm all the while, have a long and arguably distiguished history in Japanese art culture.
Not wishing to be flippant, or to use gratuitous punnage, but what the fuck is up with that? Seriously, I find the entire concept incredibly bizarre, even by the standards of bestiality and kinky satyr sex that pervades the ancient porn of other cultures. Maybe I just don’t know enough about world perversity to not single out the tentacle-as-phallus archetype as especially shudder-inducing, but presently it strikes me as something deeper and darker than most other walks on the wild side. It strikes me as a downright pathological aesthetic, and accounting for taste aside, I need either to learn I have woefully underestimated the depravity of other vintage porn, or I’ve got to get to the psychic bottom of the erotic sensibilities of the Tentacled Monster.
Please, help me out.
