Yeah, size is something I doubt we'll see anytime soon, but a flaccid dick ought to be an option by now and is well supported throughout the 3DX community.
I am a beginner Japanese married female.
I am playing with 3DXChat to have fun with other women.
The shape and size of the genitals are as diverse as the face.
In that sense, I think that it will be a more realistic game, if we can adjust shape and size of genitals in 3DXChat (even if it is stepwise).
Even in the Japanese women we have different sizes and shapes of clitoris and labia, different colors, and pubic hairs. (I can find them at public bathes (hot springs).)
Some women may be pleased to be praised for their beautiful pink labia, while others may be pleased to be ridiculed for their darkened labia which are repeatedly used for a long tarm and pigmented.
Some women have huge clitoris that can be mistaken for a penis.
(Actually there are women like "Futa" !!)
Taking Blender and Makehuman as examples, we may need an additional Rig to adjust the shape and position. And we will need to set sliders on them.
We are working very hard, currently we are wrapping up security improvements and almost ready to go into testing phase. Expect the update in November if all testing goes well, but keep in mind we can always postpone it if bugs are found in this phase. We will add a bunch of new content for you all!
