Definitely ask Alex. The only thing I can think of is "You'll have to earn those privileges" to flip the frame on her and make it clear that she has to please you first. Still, that implies that you may be ok with it and that's not great even if it does mean she has to work for it.

If you agreed with her, it might make you look like an ordenary guy. I will just chill for a bit, like her response, and play it like you receive similar text from other girls ☺️
