Scat was the first thing I masturbated to, for years it was the only thing I masturbated to and despite changing my habit in the last couple of years probably 99.99% of my fapping sessions have been to scat.

I have decided to quit scat and so far I'm doing well but I am wondering if this shit has given me behavioral problems or brain damage or something.

Should I quit scat all together or just don't touch it for a year or two?
