For a much better implementation look at the Pathfinder games (Kingmaker and Wrath).
The Pathfinder games are some of the worst examples you could have used, there isn't a single lesbian romance option option in both games, all female characters are either straight or bi, and there is only one gay man in Wrath, zero in Kingmaker, that's one homosexual in two games, I'm fine with companions having a specific sexual orientation but not if they all end up straight or bi, which is usually what happens, Cyberpunk 2077 or ME3 did it well and I would be fine with that, but it does create some frustration if the number of romance options is very limited.
This commitment to playersexuality also presents another problem as it prevents some storytelling options as you can't have a companion which is not willing to have sex with the player. So no married person who wants to get back to their family or devoted character with among other things a vow of celibacy. And neither can any story reference their sexuality directly.
That's a completely different issue, the romance options being player sexual does not mean that ALL companions must be romance options to begin with, it's completely possible to have both some player sexual companions and some already married/asexual or whatever.
