Good question. I've never asked him to slow down because I refuse to risk not seeing dat booty.
Haha! This is probably where I come in, then. ♥
Yea, Josephine's romance can interpreted that way along with other ways. Can't Dorian's be that way too?
For Dorian, it can't be the case.
I mean, you could go down the chaste route with Dorian, but it isn't the same as having an asexual character. See, should you start a romance with Dorian, he then would be pretty keen on jumping your bones first, before which you can turn him down with a "but what about a relationship, man?". Although you can headcanon your Inquisitor as asexual while in a relationship with Dorian, therefore go down the chaste route. But yeah, not the same as an established character in the game.
