questions I have about astarion romance storyline, I have lots of thoughts about him and want help from people who have played already, uh spoilers for his early romance plot below

does anyone know if you have to have sex with astarion for his romance scenes to lead up to you both working together to figure out what you both really want?

haven't gotten to play yet, and while he's undeniability charming (like he's trying to be) I'd like to refuse him without it shutting off the romance if that's an option? I'd still want to pick flirty options when I think they'd be fun but the character I have in mind would see through the more performative bits and wouldn't really be interested in sex with someone they think is lying to them, it would fit the character more if they refused.

I'm okay with mild spoilers if it relates to his story.

I feel like the answer will be no, and given the story stuff with him I've seen I could understand why, but this game has a lot of branching options so thought I might as well ask!

and if it is possible and because of everything astarion is dealing with we don't end up fucking ever that's totally okay with me
