I dont think so, unless its another addon, I can see all the content that is hidden in base game. Every time I ask her for fun it goes: "tired?... aww.."
I was wrong about it needing the mod, it definitely doesn't. (I had sex with her in an update that I hadn't installed the mods with yet>)
For me, I actually hate having her in my party. So I only do until she evolved. But what I do to get her room filled is: notice she isn't pregnant, go to my room in the tower, pick her up, bring her upstairs to the orb, back down to the room, fuck her, then drop her off in her corner.
I have never had her reject me after bringing her to the orb. Not sure what is going on in your game.
