Well... it's difficult for me to answer this, Ubantu1, although I'd like to. So I will simply share my experiences with you in the hope that some part of it might in some way be helpful with the caution that I'm now an older person. So my experiences may not really be relevant to you.

To begin with, I will tell you that I have been transgender (MtF) all of my life although I never did anything about it. (It's complicated & I'll spare you the details.) Anyway, going along with that I've had a number of what I guess I would consider fetish-like tendencies, or perhaps compulsions, my entire life. I say "I guess" because none of this has ever been diagnosed. It's just all what I know about myself & my history.

But the point here is that, as I have aged, most of this has gradually gone by the wayside. It's not that it's not all still there. If I scratch the surface, so to speak, I can still find it. But it's no longer the driving force it used to be. Part of that relates to changes in my living situation & changes I have consciously made in order to avoid triggering my "compulsions". But part of it too I presume is the aging process as well. And also playing a part in my own "evolution", so to speak, is the fact that I have committed myself to the pursuit of Buddhist practices of self-healing. (I'm no longer on psych med's, nor do I see a therapist. Neither has ever been of much benefit to me. But I have a history of suicide attempts that I cannot ignore either.)

So I guess the point here is that, if my situation is of any relevance, I would say yes perhaps it is possible to at least significantly reduce the impact of one's fetishes, or compulsions, if not to get rid of them entirely since it seems to have happened for me. However there is no clear pathway you can follow that I know of. Therapy may help if you can find a therapist who is skilled in working with individuals who have fetishes (although I don't really know because I don't see one.) Taking a look at how you live your life day-in & day-out may help... seeing if there are triggers you can eliminate or change. Finding something to commit to that is of sufficient interest to you that it takes your mind off of the object of your fetish may help. And just the passage of time may help as well. I think you simply have to find your own formula for success.

I wish there were a tried-&-true way to rid oneself of a fetish... just do A, B & C & all will be well. But if there is, I'm not aware of it. Still, at least from my perspective, there is hope that changes can occur. I send hugs your way with the hope that you might find it to be so as well.
