Never been in a relationship, or even close (lost a couple of male friends because I just couldn't go there). I also imagine that only a controlling narcissist would put up with me in the long run. Sometimes I think it would be sort of nice and comfortable having someone make my decisions for me and take care of my basic needs (sex included), without forcing emotional intimacy or for me to socialize with his friends and family. Just be kind of like a pet. I've realized that I'm mainly attracted to antisocial traits though, so this might not be the best idea ever.
I don't know whether I actually want a relationship anyway, because I've never been attracted to anyone as a person beyond the point where they open their mouth and words come out. I'm trying to lower my level of stress around people to see whether that's the reason, or whether I just don't like real-life people that much at all. My fantasy ever since I was a kid is having a robot boyfriend I can just switch off or re-program when he starts to annoy or bore me, too bad those don't exist.
