Very odd how some people who are so easily offended by the mere concept of relationships and sex, as an adult, want it banned or removed, just because they are not wired like many.
BG3 romancing options are pretty good, better than many and most games, but admittedly they do need some work, and need more options added to make it appeal to a wider audience.
But a lot of you are leaning heavily into your own personal choices or orientations and not considering a much wider audience.
Also, in BG3 you can literally just say no, or turn off the mature themes.... If you can't navigate away from relationships, romance and sex in BG3, it really isn't the type of game or developer style for you... hell it prompts you to turn off mature scenes and things at the very beginning of firing up the game!
You can even be rude to them if you really need to, or just use emotionless and dialogue-less thralls.

Whilst i agree a romance OFF type option could/should be added.
I strongly disagree with people complaining about the focus of the game being on it.
Relationships of any kind are present in every aspect of the real world.
BG3 centres itself on your chosen player arc and any form of relationship with any and every character throughout the entire game, most of which are NOT romantic, and certainly not sexual.
Just like in real life....
It has strong aspects if you wish to indulge in them, but it's a small percentage of the entire game. Some people just massively blow things out of proportion.
There are also a ton of games out there like BG3 without any adult content.

Personally, i agree heavily with the sensible comments about more options. SOME of the BG3 romance options are very shallow and if you don't perfectly romance almost every companion by the end of Act 1, they are systematically locked out by Act 2. THAT is the real problem. And once locked out or you make a mistake, there is no room for reconciliation.
You can't even apologise. You have a to re-load a save or Google the specific requirements and order for even getting someone to like you before you do other parts of the story they aren't even involved in yet.
