Ningheim problems... Suggestions?

[SkyCrime]

So I'm running my main as a Ningheim, which as you might already know is a custom race I got off the Nexus. I don't exactly want my character running around with a raging boner all the time, so I chose the flaccid Sundracon body during installation. I was using the Animated Prostitution mod, but if I chose the "Use Included Body" option with my Ningheim, the body just disappeared. Didn't happen with vanilla races. I was just wondering if anyone knew of anyway to use the flaccid body normally, while using an erect one during sex? I managed to get it to work somehow before, but for the life of me, I can't remember what installed to make it work. I haven't tried SexLab yet, wanted to be sure there was a way to get this running before I install that.

I would just suggest using sexlab. And since Ningheim has its own skin/own folder it wouldn't be compatible only if you install the meshes/textures to its folder.
