But it's obvious that the way a person smells definitely can determine attraction, whether it's a natural smell or one mixed with a sexy fragrance. And smell can be a turn-on for a lot of people - body odor is definitely an established fetish, and there are even so-called "pheromone parties" based on B.O. In New York and other large cities, these mixers feature non-artificially scented people bringing t-shirts that they've slept in for three days, then putting them into a numbered plastic bag. They sniff, choose their favorite funk and have their picture taken with the numbered bag, which is then put up on a large screen. The owner of said funk can choose whether or not to approach the person who likes their smell. Does it work? Who nose?
