Hello,
Yes pornography addiction is a mental health issue and will require treatment. Behavioral addiction is a significant mental health disorder and sexual/pornography addiction falls under this group of disorder.
Hence my suggestion for you is to please seek a consultation with a psychiatrist for comprehensive assessment and further management. Some medical causes of sexual hyperactivity will need to be ruled our, thereafter a combination of medication and psychological intervention can be provided.
Hope this helps you. Best wishes for your health and future...
