This is essentially my problem with having herosexual NPCs, as I said in another thread
If my character's romance as a woman is a copy and paste of their romance as a man I consider that a failure of writing, because it doesn't reflect very common world experience, even for a high-fantasy medieval one.
By that token if every companion is just a vessel for my MC's attention, it detracts from their characterization.
The problem becomes especially fraught considering we could be playing every origin character with whatever sexuality we want, but they don't always act that way when not being piloted.
