This obsession with who might or might not be a post op is madness. I think some people actually get off on it. From my view, I've seen a shed load of Asian escorts from crappy Chinese flats, VS b&s to proper Thai escort girls and in all that time I've yet to come across a repurposed inside-out ball bag or whatever it is they do to make something that can at best look like a mutilated minge; so I'm pretty sure you're worrying about nothing in 99.9999% of cases
