What about erotic fetishism?
Would you consider fetishism as bad? Some dictionaries have it as a form of sexual behaviour in which gratification is linked to an abnormal degree to a particular object, activity, part of the body, etc. Somehow I don't believe that anything within reason is abnormal. What about all those desires that stay dormit and don't appear in someone's behaviour? No, personally, I don't consider a foundness of hosiery as such as being bad. How about you?
