I just want to start by saying that I absolutely love this game! The characters are great, and all of the romances are extremely well-written. With all of that being said, however, there is one thing that has been really bothering me. Every romance option except Wyll requires the player to consent to a sexual relationship in order to pursue a romantic one (you could bring up Astarion, who later shows interest in a romantic relationship without sex, but you still need to have sex with him in the beginning in order to get to that point).
I would like to suggest a dialogue option where you can ask for a non-sexual romantic relationship (even if some companions wouldn't be happy with that). This could essentially toggle whether or not your character has sex during the romance. This option would be great for players who are asexual (but not necessarily aromantic), players who have complicated relationships with sex, or even players who just want to play a character who has taken a vow of chastity (like a monk or cleric).
I know it would be a lot of work just to include this one option, but it would mean the world for people who currently feel excluded or uncomfortable with the current romances, and Larian has clearly shown that player inclusion and safety is a top priority (I don't think that I would even be suggesting this if I didn't think it would be taken seriously).
