I have never before found anything physically positive in people, am I crazy?

My entire life, I never had the raging "she's hot, she's really hot, ewww, she's fat" discussions with fellow peers as most guys had. I guess I have always been somewhat reclusive, never seeing beauty...never finding any girls to be hot, or pretty, or cute, or attractive. Maybe I am severely narcissistic, but even the "plain" girls would practically melt before my eyes into something terrible. I'm not a mean person, and in fact, most would describe me as an incredibly sweet boy, just perhaps a little shy. Quite possibly the ugliest face I've seen is my own (well, there goes the narcissism theory), I unfocus my eyes in the mirror as to not look at myself directly. Then one day, working at a cafe, a STUNNING beautiful girl comes in, and it was fireworks and music and the sort. I have been with her for 4 years, and her beauty still makes me want to weep. Am I crazy...or is this a perfectly acceptable set of feelings?
