There are very loud people in the community that feel they are "above" sexuality in Poser art.  If one enlarges a breast, they are vocal about it and usually kind of snide and condescending...much the way Max users used to be about poser users back in the day where poser renders were puke awful.

They rule on high from their Ivory Towers and for the weaker people amongst us they become afraid to even share their work and raise awareness.

So it seems that the pruder, puritanical set is larger in number and it is imagined that the market should cater to that.
