Almost Relapsed to Non Sexual Image

I’d been feeling like a relapse was coming today after 5 days and the feeling intensified when I saw a picture of someone on my instagram feed which led me to looking up more pictures of that person. The lust finally settled on an image of that person fully clothed and sitting in a slightly provocative way but not the most sexual way. I sat down to do the deed when about halfway through I just got completely disgusted with myself and stopped immediately. For me doing it to a picture counts as a relapse because I know this lust is using whatever it can get its hands on to keep me in this trap. Just find it strange that this time where 9/10 times I would’ve failed and been back to square one that my brain almost hit a failsafe and stopped without orgasm.
