Never heard of this particular fetish, but it sounds like a challenging one to deal with. First, I will say that no doctor would perform a surgery to make you incontinent. In fact, I would strongly advise not telling a medical doctor about this. Doctors do not have training in dealing with this sort of thing, and they may behave in a way that comes across as judgmental. Instead, you should bring this up to a mental health therapist/counselor. They have more expertise in dealing with things like this, and they do not judge their patients about these things. Chances are a therapist could be very helpful for you to be able to deal with or possibly move past these feelings.

This must be a very difficult fetish to have, because being incontinent is a daily struggle. There are also health concerns that stem from incontinence. It must be difficult, because being incontinent is really something that no one wants....... yet if you find it exciting in a sexual way, it is likely to lead to difficult, conflicting emotions.
