What I want is 2 things:
-Let us hug our romanced character, dammit!
This is really noticable when you romance Shadowheart. At the end of ACT 2 and with her personal quest. She is there alone, questioning herself, her life choices and crying, while my character just stands like a moron. You should be able to hug your companions, only Karlach and Astarion get a scene like this, last I checked.
-If you romance someone they should be sharing the bedroll, cuddling.
Just a little bit of reactivity, holding hands, etc. Just not asking for a kiss.
