Yeah I was going to point to Cyberpunk as an example of player-sexuality misfiring. Unless your character was bisexual you only ever had a single potential romantic partner, take it or leave it.
And that is fine. BG3 is not a dating simulator. Not getting your preffered romance is much better than making every NPC bisexual/playersexual for romance while the rest of the character is written completely different (or having to write each NPC as bisexual in the first place).
