Hey I am 22 years old, when I was 18 I started masturbating and starting doing it like 4 times a day sometimes 5 now that I'm 22 I find it hard to rise to the occasion I really need help cause this is really frustrating.

You still should at least when you masterbate, you may find it hard to stay hard in normal sex since there tightness or feel is not the same. Things from stress, to medication to illness can cause this issue, perhaps time to see a doctor
