If the therapist reinforces a perception that these impulses you tend to have and your ability to just keep them inside and not act out is bad, then I am not sure who is bad actually... Would not sound like a good T to me, someone "helping" to maintain an obsession by looking for a source that may never be found or does not even exist other than in your physiology. Instead of encouraging you to look at it differently. What does it matter really whether you were born this way or acquired it? It reminds me when my first T insisted that we should keep looking for the causes of my addiction in my childhood because otherwise I will never beat it. So untrue! There really is not much useful information in my childhood history that helps me maintain my recovery, not even to explain why I am prone to it. Of course one can always explain it in a million ways but, the truth is, I simply just loved the momentary pleasure and the euphoria and made bad decisions focusing on that in the moment while neglecting and escaping real tasks in my life. I actually even stopped going to recovery meetings after a while because I found so many people there traded their old addictions with obsessions about recovery and many would be quite harsh claiming whoever stops going will relapse shortly. It did not happen to me, I relapsed when I was overly engaged and obsessed with therapy and trying to do everything by the book in recovery. I am not suggesting this is the case for everyone but have seen quite a few people similar to me in this regard. It's been far easier for me to accept that I probably will always have addictive urges every now and then, it is just part of me. Trying to wish them away or looking for mysterious solutions to eliminate them does nothing more but reinforces them and makes the urges less manageable and contained. Even just a perception that there is something wrong with me... it is not useful at all. As long as the urges remain inside and I don't act on them in destructive ways, it is not wrong at all, just a bit distracting and challenging sometimes. I think we all have our individual versions of such challenges and they are often life-long. It can be much more constructive and realistic to learn to manage them rather than trying to find where they come from or to aim for eradicating all of our flaws.
