I said it countless times and will repeat it here ...
Im glad that someone finaly broke that stupid cliché (yes, i know Dragon Age Origins, or Inquisition did that aswell) that game romances have to be stretched over whooooooole game, where despite the fact that our characters litteraly risk their lives every minute in the world, they decided to "wait for that perfect moment". -_- Yes, very romantic ... and also very stupid.
Especialy in cases like Mass Effect 2, where catalisator of that romance scene is "that you starting your suicidal mission and may not come back" ... how exactly does that differ from litteraly any or every landing on un-civilised planet?

Nah, this makes perfect sense to me ...
World is dangerous, we like each other, there is opourtunity ... so why not?

But yes, it would be nice if NPCs would have their own sexual prefferences ...
Wich ties to my suggestion i was also repeating several times around here:
Followers should have 2 prefferences, gender and race ...
If our PC fits both, they should propose relationship (presuming we have enough approval ofc.)
If our PC fits one of them, they should not propose, and should get alterned dialogue in case we express our interest in them.
If our PC fits none of them, they should not propose, and should get again alterned dialogue, where they will be extremely surprised by the situation ... but can potentialy keep open mind to try it, in case Larian want all our characters to be romanceable no matter what we create.
