People often find talking about the human anatomy distasteful.  DAZ has yet to produce a complete figure of a woman with the proper parts.   Victoria 4 still is missing a vagina, I don't understand what the big deal is, I mean why they don't make a woman with one.  The current run of native poser females have vagina.  M3, Freak and David have only what I would condersider to be poor represenations of the male anatomy, but at least they have it, not just a GI Joe blank groin.  Those who don't like such things are free to turn it off.

I think it's fun to joke about such things since we can at least discuss the topic without a huge out cry.   I think, however, the folks on the Renderotica forum could offer a more serious reply and have methods to achieve the desired effect, Blond Bear is particularly good at simulating all the various effects desired.  He can be very helpful with posing tips, perhaps the author should send him a private maessage on the subject.
