question: Hi doctor,I am a 24-year-old male with no health problem except for my problem with premature ejaculation and no second erection. It is very frustrating to last 2 to 3 minutes in the preliminary and then my desire goes down. I had a problem with internet porn where I can have as many erections as I want. I am one month free now but premature ejaculation has always been there. I also cannot hold my pee for a long time. If this can be associated with the problem, I am begging for help beacause it is ruining me and my relationship. I am taking corticosteroids for autoimmune disease.
