I think I'm just better at preventing romance than most people. In my current playthrough neither Astarian or Lae'zel wanted to sleep with me. I don't mean to brag but I'm pretty good at this in real life as well.
This made me smile

. It also made me wonder though, she Astarion rejects us now, do you have to broach the subject with him or is it like how it was with Laessi (at least previously, I haven't reached that far on patch 4) and they immediately start telling you about how you could be having sex with them if only you had made the right decisions as soon as you initiate dialogue as if you could have no other reason to talk to them?
Because the only thing that annoyed me more than the "everybody wants to fuck the PC at the same time" immatureness was the "everybody who don't enough approval to want to fuck you
also have to make that known to you at that very moment" ridiculousity.
I just want Shadowheart to stop disapproving on Astarion's romance scene, please. PLEASE. Why is that bug still there even when they've taken out the cinematics.
Shadowheart doesn't approve of food sex!
Also since SH approves of Scratch petting she is one of the easiest to always be able to have a relationship with by far.
From my pre-patch-4 playthroughs it always seemed like SH gets improvements in smaller amounts than say Gale, possibly because different writers/coders. Gale is like super buddies with you after just a few interactions but SH lingers in the neutro-zone much longer. I've had to abuse the Scratch exploit to actually make her approval go up to the high class before.
