You are not forced to engage in romance at all, you have the option to say no. If you want to go through the entire game without romancing anyone then you can do so, because it is an option. Just like how Larian has it as an option where the player can bang everyone in the party if s/he wants to. If you want to play a sex crazed player then that is on you or if you want to be celibate and not do that. Then again you have the option, you are not forced to engage in romance at all. I seriously cannot see how other people can not see that romance is "Optional and you can say no" and it doesn't destroy immersion.
