I don't see Ayumi as a sex symbol, though I do recognize that she's been trying to make her image a little sexier each year. Unfortunately, more people judge by looks more than by the actual personality of an act. I'll tell you right now, there are some really innocent sounding J-pop songs by innocent looking groups (especially in the past) but if you ever listen to the lyrics closely, you get taken aback by how risque they are. With the porn star remarks, it could likely be a product of the fact that there are a LOT of mislabeled files on Japanese fileshare programs claiming to have a nude Ayumi picture, etc.
