Relationships/sexuality in video games always feel forced and stupid and never really add anything significant to the game play.
Don't think so. Relationship or/and sexuality are the same part of character as STR, DEX or WIL. Or should be/could be.
But...
It is not a part of system or “too much sex/romance thingy”, it is just a case of overcrowded and too small game world, destroying illusion of “harsh post war environment, where every drop of pure water, every bit of women, every chunk of man counts”.
