ADHD and masturbation/porn addiction

Sorry for the sensitive question but does anyone else struggle with masturbation/porn addiction?

I work from home and it’s honestly ruining my life. It has become my go to form of procrastination and it’s really effecting my mental health. Whenever I get stressed or overwhelmed it’s my go to. Even when I’m not horny at all I’ll start watching porn to make myself horny. Sometimes I can watch porn all day and lose hours of my life and it makes me feel gross afterwards.

I have tried going cold turkey but it never sticks. I’m at the point where I’m thinking of getting therapy around it.

For context I am 39, recently diagnosed and medicated, lots of areas of my life have got loads better since being on medication(about six months) but this is one area that if anything has got worse 😭

Anyone got any advice or anyone else suffer with this?
