Is there a way to prevent the Astarion assault cutscene?

I'm referring to the bit in which he bites you in your sleep early on. Considering that vampirism has a history of being about sexuality, it's pretty weird to me that he bites you when you're unconcerned and not consenting every run. I want to romance him this run but want to avois that scene because I certainly wouldn't want to date someone who sexually assaulted me roleplay wise. Is there a way around this scene or does it always trigger?
