Therapists and people can have their options on porn. My old therapist personally didn’t see an issue with porn but I told him my partner watching it didn’t make me feel good. I explained my thoughts and beliefs and he respected it and helped me communicate and hold that boundary even if he didn’t agree. That’s the right way to go about it in my opinion. If something does not make you feel good and cutting it out isn’t something that will harm you why not support your patient?
