Am married from past 3 years. I had a normal sexual life for 6 months. But later gradually my interest towards intercourse is reduced. I was more interested towards masturbation than an intercourse. Now I am facing problem with my erection. I get erected only when masturbating but not for long...within few mins, it will be gone.    For history, I started masturbating at the age of 18. And I was masturbating for long hours at night. Usually I used to masturbate at least twice a day whenever I get time..
