Introducing G4forMen Ultimate by Insomniaworks, The3dZone, and Khrys
This is the most difficult that I and may partners have ever developed.  It took four months to perfect and involved much testing and experimentation with three prototypes prior to developing the final geometry.
This Penis was set up to work specifically on Michael 3.0, but has plenty of options for making it work across a spectrum of  characters.  It can be smart propped as well as conformed and has special morphs installed for fine fitting to other characters.  It comes with both Tone adjustments to match DAZ's standard tones as well as Brightness Adjustments.  
This penis is different in one way from all other penises because this one was modeled in an erect position.  I have always wondered why penises were modeled in a flaccid state because the they tend to not look well when made erect.  This was done opposite, so it looks it's best when erect.  TOS does not allow me to show this product in the erect state.
The Penis contains twelve groups in this order: Scrotum, Hip, Nine Shaft Sections, and Glans.  The nine shaft sections seemed just enough to do realistic poses with out sharp edges, while not being too many being overkill.
This product is Jam-Packed with Morphs all operated from the Body group.  There are Thirteen morphs in the Scrotum,  Four along the Shaft, Eight in the Glans and Four morph in the Hip for adjusting Fit.
