amputee porn is actually fairly common... i remember reading an article about it in Jim Goad's ANswer ME zine like 15 years ago...
i don't know Zhao, that HR Geiger dildo looks like some boring industrial/fetish culture bullshit thing... like you need to burn incense (or sage), put on a pleather corset, and listen to Peter Murphy before you stick that thing in yr twat... yawn, no thanks...
that whole ULTIMATE DILDO thing is def a mostly male fetish of WHAT GIRLS LIKE... like all those FUCK MACHINE pornos (whatever they call that thing, the Sybian?)... reminds me of G. Clooney in Burn Before Reading... i mean, i am not denying the ladies like them some removable showhead action or a pocket rocket, but when it becomes some weird machine with like 5 different things sticking out of it, like one for the asshole, one for the clit, one for the g spot, one for deep penetration, etc etc etc, it doesn't seem like a woman designed it for a woman, it seems like a perpetually flacid perverted old german scientist (just go with me on this...) thought it up while wiping drool from his gumless mouth...
