If they imagine the Astarion - Tav (or Tav - any other companion) romance a certain way and it does not align with your personal preferences, though luck. It's not a failing on Larian's part.
You can literally tell Astarion you're not scared of him but then you're forced to act like you are after a single patch. You can also rule with him now and you are clearly in charge, not him - you are a power couple in that scenario, not a scared little girl/boy who can't handle their partner's intensity.
