Perhaps its my heterosexuality, but an orifice full of goo has never really appealed to me, unless the orifice in question is my mouth and the goo is Marshmallow Fluff squeezed out of a paper funnel.
Consequently, I am both repelled and fascinated by the concept of pouring liquid latex into a vagina and allowing it to harden to form a permanent cast. And at £800, I'm not quite sure who would buy an inside-out latex vagina (resembling, in this form, some sort of translucent pink alien polyp). It's not like it's a cast of Mother Theresa's vagina or anything.
