Hypocrisy, thy name is Amber

I have gone on the record as being a fan of men 1.5-3 times my age, but I find it gross and weird to consider a relationship between an eighteen-year-old and a thirty-year-old. A one night stand I could be okay with, but that age pairing, dating, just gives me the willies. A equal age disparity between older people (30 and 42, say) is not objectionable. Am I alone?
