Well, you'll love me then! I don't even use a towel after showering; I just look at myself in the mirror and admire myself while drying off ;)
Seriously though, I don't think I'm a narcissist and have not dated a narcissist. But I would think you would have luck in dating a fellow narcissist, as I don't believe in the phrase "opposites attract"
Do you know how it is that others bore and annoy you eventually? Is it that you find them genuinely unimpressive or something else?
It is okay to be confident in who you are, but it is also important to accept your faults. You are not perfect, just like me or anyone else. In order for you to change, you must first try to figure out why you feel like this in the first place. I do know that it is possible to have a stable relationship when you are narcissistic, though it may require some change.
Two ego-centric people in a relationship? I don't see how a relationship where both parts always put themselves before everything else could even remotely work, that's like a cat person and a dog person sharing the same house with all their pets lmao, but ok..
