First and foremost, congratulations on such a monumental feat. I would kill to go on that kind of streak personally, and you should be very proud of yourself. In regard to your experience, I wouldn't consider it to be something serious. A relapse is when you deliberately seek out pornographic imagery which generally leads you to PMO. You did not look at porn nor did you even touch yourself. While pornographic thoughts/fantasies are technically relapses you should avoid, it sounds like yours was a case of an unwelcome sexual thought that you made a conscientious attempt to resist, which unfortunately ended in orgasm. The fact that your brain is so desperate to get dopamine that it would allow you to orgasm at a mere sexual thought is actually a good sign and a testament to how far you've come in your reboot. I would say that this was an isolated unconscious incident that was involuntarily brought on by the brain and shouldn't be treated as any sort of relapse or defeat. The only thing you should be cautious of is your urges in the near future. Your brain got dopamine and it's only going to want more. Your urges to PMO might be stronger for a week or so, but if you resist them, you'll keep moving forward as though nothing happened. Also worth considering is what you were doing prior to these thoughts entering your brain. Did you encounter a trigger? Or even a trigger of a trigger? Was there something you could have done to stop it or can do to prevent it in the future? If the answer is yes, work on it. If the answer is no and the urge came out of the blue, then you were simply the victim of your own brain in its desperation for dopamine and you really shouldn't worry about it. Don't read too far into this one.
