wait I thought when Val said they weren’t gonna stop she was referring to their relationship not sex??

Hmmm. You think so? But why would they even be discussing their relationship in the context of stopping or not at that point? I totally read it as them talking about not wanting to stop until they were interrupted. Granted, they probably would have at some point anyway, that not being the ideal place for any of what it was going to mean to them, but I think it was more a nervous testing of waters to see where they stood.
