Night falls are common in unmarried man at that age. It wont cause any erection problems. Its your pschological fear about night falls which is causing such lack of strong erections. Sperm is daily produced and it can not be stored indefinately in testis till you start your sexual life after marriage. A healthy masturbatory practice one or two times a week prevents night falls too in unmarried man. Okay?

Hello there. I can understand your concern. Masturbation will help you overcome this. what happens to a pot when it's full and you still try to put water in it. It overflows. Night falls is like that. Masturbation upto thrice a week is good for you. If it still persists, get it checked out by a sexologist in person for further evaluation and management. Best regards.
