To add my 2 cents, it's quite bizarre, when you choose a companion at Tielfings party and yet I still had both Gale and Wyll hit on me. It gets worse, as you pretty much agree to make your chosen relationship work.
The simplest fix? MAKE THE PLAYER BE THE INITIATOR + Make it obvious, when a comment is considered a flirt. If I show no interest in my companions, then either they shouldn’t do anything at all or be MORE SUBTLE:
Something like:
"Hey, if you don’t mind me asking, what are your feelings about love?"
Or
"Would you like to spend some time alone together?"
Seriously, I try to get high approval with everyone to help them with their problems, not to sleep with them. If I wanted to see sex, I would have browser the internet.
Your complaint is irrelevant because the final choice is yours
