Talk to Andrologist on Night Fall And Erectile Dysfunction Premature Ejaculation

Assalamu Alaikum, my name is Ahmed and I am 18 years old. I became very weak and depressed due to constant masturbation from 2021 to 2022. Then I quit this habit, but after that I had nightfall every week. It has been three years since I had this disease, due to which my penis has become very small, soft and flaccid. Please help me get rid of this disease. I am very worried.
