I'm also curious about cultural preferences (if any) towards certain notes. I had never heard of Kouros or anything like it before I met basenotes, and yet here it is- a best selling frag.
Americans are brainwashed from day one that any odor, blemish, imperfection, or other flaw instantly renders them sexually unappealing and they will die alone because of it. I don't know if it's that bad in other countries. From what I hear, there are people who enjoy a more natural smell on other people- not unpleasantly rank, but not as clean as freakin Windex. I have yet to meet that kind of woman here in the states (well, I have met that kind of woman, but she has bad odor problems of her own )
I would like to live someplace where I could go out wearing Kouros or some other blatantly masculine frag and feel confident that at least SOME people would enjoy it for the same reasons that I do. Wearing Kouros out where I live would be like shaving only the left side of your face. People would stare.
