I need help finding the right kind therapist

(Sorry for the long story) So I've had a porn addiction for a long time. Im 21 and it's been around for many many years. Throughout my school life I was very alone and I did watch a lot of porn. But then it sort of evolved into me taking screenshots of girls i knew and using them as material. Flash forward to now and it still exists. I have a girlfriend now and she means the world to me. We've been together for almost 3 years and she found out about my problem and she know some of the people I use a material and I really broke her heart and I just feel horrible. I never felt good everytime i did it but i still eneded up finding myself doing it. She still says she loves me and I promised her I will make it up to her. I've installed a website blocker thing that does work to start things off but I want to find a therapist to help me with the pictures sort of deal. I don't know if i need to look into like a sex addict therapist (I am a Virgin and so is she). I just want an arrow in the right direction.
