If you went with "I think we'd get along then" you should definitely soft-close here. I also think you missed an opportunity to sexualize here as you could have gone with "So sex on the beach then?" or something a bit outlandish that incorporates sexualization a little. The reason behind that is, this role-play of "adrenaline activities" allows you to play it off as a joke after was she to respond poorly to the escalation if that makes sense.
