why no selection in the action
I see two explanations:
1. It appears the screen didn't fully load, which can happen on low performance devices. Or
2. Your relationship is set to 1 or 0 (in the latter case you will never get in her pants), making lust a problem without copious amounts of potpourri and incense.
I would try from another save, setting her relationship to 4, pot on some potpourri and getting some scenes unlocked like longing. Mixing pink leaves into her tea is another way to increase lust.
If that should fail, remember that how you answer when she wants to bang you will influence your relationship going forward more than you realize.
Lastly, a direct dm to Mk41 will always be more effective than an @ in the comments.
