There are also genital morphs @ sharecg.com for free.  If you use the DAZ genitals, be prepared for major within Poser when applying and conforming them.  You will get 2 full figure models when you pose the original.  The second figure will not pose.  My only workaround with this problem is conforming the genitals in DAZ3D, save out the scene and import the DSON with D3D's DSONLoader.
