At the end of the game, she doesn't bring up wanting to visit Halsin (a trip to the druids Grove as you put it) She doesn't say anything about adding anyone else or wanting anyone else in the relationship. So those optional 5 minute porn quests have no consequence on the actual relationship.
You can headcanon all you want, but at the end of the day, she ends up with Tav only and there's nothing to indicate there's anyone else sexually/romantically included in this.
She doesn't exclude it either - be strange thing to bring up then wouldn't it? Right now you are both homeless. Time to think about getting off the streets and then you can think about Saturnalia.
