To all of them. At the same time. All of them are trying to bang you early through the game during the same scene. You can say no, that doesn't make it any less weird.
This comment reminded me of my nightmare settlement in FO4 where my companions lived. I had approval maxed with all of them but had turned them down for the relationships. Every time I went to that settlement, they all started slowly converging on me like zombies because the relationship dialogue trigger was maybe bugged and they couldn't take no for an answer. Was really creepy.
I wonder if for this there couldn't be some early trigger that would possibly set a friends only status. Maybe in a camp conversation that had something to do with relationships in general and you could say something about having more important things to worry about. After that then there would be no advances by anyone and if you changed your mind later you would have to do a lot of work to get someone interested.
