I'm not so much bothered about Dawn's lack of genitals rather than about her male companion.

Stylized female genitalia for simple nudes can be made with a magnet or two from the base mesh and detailed ones need an add-on prop for all the inner bits anyway.

But unless 3rd party male genitals copy exactly the UV-mapping of the base mesh, it's very hard to avoid a nasty texture seam in the pubic area.

And a lot of texture artists will create male textures without matching genitals because there is no "official" version around.

So let's say artist "A" makes a texture set for Dawn's male counterpart.

Then artist "B" makes a male genital prop for Dawn's future mate.

He would need to "borrow" a few pixels from "A"'s texture so that his genital prop matches exactly to the body texture.

I do hate postwork, and I don't like to "mix" different "brands" of figures.

So this problem would also limit Dawn's use for me.
