I have this PE problem. When I watch pornography I can't withstand for a minute. It's all because of my masterbation. I used to masturbate by the mind of have to done quickly. Now it's continued. And I feel anxiety during the sex. I lost within 5 to 10 penetration.but I can stand while masturbate in normal time. I feel like it's a mental disorder. It's curable or? Give me the solution..I want to become best one
