Except you're never forced to be in a relationship with anyone except the person you choose to be. So it's not an issue.
It's not like you're forced to have a relationship with every companion. In fact you actively have to select specific things to be able to get into one. If you don't want to romance a person, then don't. Then their sexuality is irrelevant.
I agree with that. Playersexuality doesn't automatically mean the player has to accept all possible options.
Outside of stuff like conversation bugs or, of course, temporary misunderstandings (which can also happen in real life, ironically enough)...nothing in the game forces you to pursue any romance with someone that you're not interested in.
If you've made a mistake or if the dialogue wasn't clear, then you can usually say "no" and simply put a stop to any further progress with that person.
Playersexuality can be played completely straight or completely queer, or somewhere in between. It's all open to preference and up to the player's choice.
