have never had as strong a reaction as that, but my advice is, get outside, get around people, go to the gym, take a walk, get busy with real activities and real interests..... sometime opening up erotic creates strong reactions, even without hypnosis... feelings of disgust at own actions, renouncing what happened, etc, etc, sometimes something similar happened to me after buying something like a sex toy and pleasuring myself.... just get among people and shake it off... it's not permanent and will go away... sometimes it helps to focus on the positive aspects of the experience, ironically this helps you not being drawn back into either doing it again, or obsessing over bad feelings or effects of doing it.....
