My problem is that when was 13 year old i started doing masturbation and watching porn exessively a lot of times daily .and i am doing it since 4 or 5 years....and now iam suffering from premature ejaculation...means...i discharge in very less...time during masturbation. And i also noticed...that quantity if...sperm is...less and...the size of penis...is somewhat smaller than usual size, although there is no problem in Erection of penis So if i give it a gap of some years would it will improve
