erogenesis:

 

I believe this problem originates well outside of the Poser Art community.  A huge amount of people are still sexually repressed and this repression usually takes itself out on the female form or on female sexuality in general.

If  female has genitals, then they are potentially sexual.  If no genitals, they are "pure" and therefore no sexual shame in enjoying their form.

Not so true on a Male, because can have genitals yet be portrayed as "flacid" and asexual so there is no shame in a flacid penis.

Even a Ken Doll has a noticable bump where a penis should be, but Barbie has nothing.

 

What I find fascinating is that somehow everyone that creates a brand new human female figure has the same mindset, that genitals don't belong.  I think the more talent an artist has, the more they are afraid to tarnish their reputation with the idea of sexual perversion for taking time and effort to sculpt Vag. 

 

A few new figures over the past had included genitals, but the figures were useless.

Ero, take this idea and run with it if you like:

 

I've always thought that the xxx Poser users could benefit from a highly articulate Torso for close-up action shots.

 

Hip, Thigh, abdomen, chest, upper arms and neck.  The focus of course being on the genitals and all that they could do with a LOT of polys.

 

So normal figure for wide shots with head and everything and an articulated torso for closeups.
