I ended up backing up all my mods other than the "Devious Desires" related mods, then deleted all mods in the mods folder, I then re-downloaded all "required mods" listed on main page and installed them into the "Documents/Electronic Arts/The Sims 4/Mods" folder, then put the contents of this mod into the same folder, I also put a copy of the mod_data folder in "Documents/Electronic Arts/The Sims 4" folder, just to be safe. with this everything is now working. all I had to do after was put all the backed up mods back into the "Documents/Electronic Arts/The Sims 4/Mods" folder. I hope this helps, I'm not sure I was very clear lol.
In short I put "mod_data" in Mods folder and "The Sims 4" main folder, and this worked for me.
I have the mod working, the only problem I am having is, people keep masturbating with invisible objects, am I missing an object file? and If so where can I find it? I am currently just using the default animations that came with the files. EDIT: Another issue I found was (female) failed to impregnate (male) .... uh... yeah, but why didn't the female get impregnated? why is the male always the target when he is giving it to her in the V?
