In recent versions of Poser you no longer need a separate prop to host a hair growth group, which might make things like body or facial hair, where the hair growth group needs to adjust to morphs or joints, easier.  You should be able to use the Grouping Tool to set up a hair group on your hip actor, for pubic hair.  Then grow the hair and play with the Hair Room settings to see if you can get decent dynamic pubic hair out of the process.  I tried this with Antonia, a few months back.  It worked decently, but Antonia's hip geometry didn't permit me to group polygons such that I could get a decent-looking outline for the hair in the area.  Dynamic hair may also have trouble doing tight curls such as one sees with body hair.

Another approach might be to build a conforming figure, using a series of specially UV-mapped ball props for the geometry.  Then transmap the props and copy the weights to the conformer from the conformee.  Depending on how you arrange the ball props and how well the UVs and textures are set up, this might work decently.

Using either of these approaches on top of a texture with the "flat" body hair painted on might help add a layered quality and more closely approach the desired effect.

 

Edit: I should have read the link, posted above.  The dynamic stuff is already covered up there.
