Just a note worth considering. In general society we bandy about the word 'fetish'. Anybody with unusual sexual preferences (bondage, urine, pain or, yes, even crossdressing) can be said to 'have a fetish'. In psychological (ie professional medical) terms a fetish has a very specific meaning.

Is a good starting point, specifically, we shouldnt think of a fetish as being a disorder:
'It is only considered a disorder when fetishistic activities are the foremost source of sexual satisfaction, and become so compelling or unacceptable as to cause distress or interfere with normal sexual intercourse'
Hope this helps...
