Oh! Actually, there is an oversight there which blocks moving forward, so thank you for pointing this out; you will need to go ahead and have sex if you want to continue progressing with her.
Sorry about the confusion, thank you for bringing it to my attention though!
Not a problem, happy to help. I usually make a save before I make a decision like that.
Edit:
I think I found another issue. I seem to be stuck waiting for Alicia to "get situated" after the scene with her at the safe house.
At the same time when I visit her at her house there is a prompt to visit Lady Mantis that I don't remember having set up with her.
