Inappropriate sexual triggers

I don't know if this has been discussed much on here, I did a search under sexual disorders and found a little bit about triggers, but I think this is more of a dysfunction than a disorder. I have some inappropriate sexual triggers, they started as a child. It doesn't seem to me that sexual triggers can be changed or stopped. I have seen many psychologists in my life and I only had the courage to bring this up to one of them, her only suggestion was to enjoy it, but if I am out in public or at a friend's house and I am triggered, it is NOT enjoyable. When masterbating, I try not to think of these triggers, I try to think of "normal" turn-ons, but that hasn't helped them to go away at all. I guess I'd like to know why this can't be fixed, why the link to these sounds that turn me on cannot be broken.
