My sole question is, are there other things about them that attract you or are you attracted to being attractive to others? What I mean is, when someone is attracted to you, does anything else matter about them? What about their personalities or physical looks? Anything? If it's simply that they like you that might not bode well for long term relationships since after awhile even when both are attracted, the initial infatuation or "fire" goes down a bit and we're left with whatever's left and if there's nothing beyond that factor there you'll get bored and won't find anything in them anymore.

On the surface it may not seem like a bad thing. You can't be with someone that isn't attracted to you so it works fine but if it's the only thing that attracts you, I can see this as a problem.
