Relations of that kind do not fit well with my previous Larian experiences. I'd prefer not having that int he game. Romance though might work, as an optional kinda thing. The theme doesn't bother me, I just don't think it is something worth spending much time on as there are other games out there with a dedication to do that sort of thing really well. Here it would have to be rushed in, and might end up a bit weird.
Romance: Yes.
Sex: No.
