BG 1 and 2 were 20 years ago, created by totally different people, with a different demographic, goals, and crpg culture, There is no reason to expect the same thing.
Which are actually some of the same devs that wanted to put more lgbt content in BG, Mass Effect, Dragon Age, and Kotor, but couldn't cuz they'd get greater push back as these romance scenes are getting.
I'll never get used to people going "gore, blood, guts, slavery, torture, are all ok and I'm ok with my child playing these video games and have fun" but oh NO sex. You let your niece watch your character pull out a living brain and kill someone? Replace your argument with violence.
"You ruined my role-playing game with violence. It's my PERSONAL OPINION that there should be no extreme gore like pulling out a brain from a human skull because Baldur's gate never did that."
I understand you don't want to experience the sex part of this game....so don't. You have every right to not want it and not everyone is comfortable with sex on the same level as gore, violence, etc.
But you went on a specific path, made specific choices to reach this specific scene, and said "no not for me and it's ruining my game"
Make a different choice. Shadowheart as a cute little date scene instead or don't romance anyone. Those choices are really satisfying. Having that sex scene with Minthara and making the right choices to get her to soften up was actually really satisfying. You also have choice in being the dom or the sub in that scene depending on some rolls so more roleplaying there.
Personally I think Larian will implement adult content filter. Hopefully
