It's incredibly disappointing. I was playing his romance and wanted to at least discuss what "taking things slow" meant - because that doesn't necessarily mean no sex, but it does to Wyll. Can we at least discuss some boundaries and expectations here, Wyll, if you're going to force celibacy? What does a storybook romance mean to you, Wyll? No idea, really, and because he doesn't talk about it it comes across as a bit of a sex negative punishment. There's a few moments where it becomes clear that it was supposed to be discussed but only after you've slept with or discussed sleeping with someone else (eg. the drow twins, the "It's only sex" line after sleeping with Mizora), but as a couple you two have never discussed sexual expectations whatsoever. I don't need a sexual encounter in every romance, sex is not the be all and end all and intimacy means different things to different people, but I would like a discussion of boundaries/what it means to Wyll AND some sort of scene of equivalent intimacy.
His previous romance scene from EA springs to mind. There was no sexual encounter but you cuddle together through the night. It was perfect.
One of the developers posted publicly on twitter that Astarion has 4x the amount of different hellos for romance stages than other characters. There's no one you can feel it more strongly with than Wyll.
