This was the result of some experimentation with Blender's fluid simulation to find a passable semen simulation. The result is not perfect, but it's decent, so I thought it was worth sharing the settings.
The fluid cache was several gigs in size -- too big to upload -- so you'll have to bake the simulation before you can render it. It'll probably take a long, long time even if you have a fairly powerful machine.
