Without wanting to sound like a NoFap cult guy, I'm just dropping by to say give up watching porn. I couldn't jerk off for a while due to travelling and this weekend, when I got back, I had a huge binge and felt truly disgusting. It made me realise and admit to myself that I'm addicted, and I had a revelation about how truly fucked up it is that I, most probably like you, was first exposed to porn when I was 11 and have been watching it since. It was there throughout my formative years and (statistically) through yours, and it definitely affected my attitudes towards sex and my sexual behaviours in negative ways. It's shit for your health, your outlook on life and a horrific industry built on rape and exploitation.
Give it a go. If you can stop watching it, stop watching it. If you can’t stop watching it, then DEFINITELY stop watching it (if that makes sense)
