I'm 17 year old male. I have struggles getting a penetration strength erection. When i masturbate i can sometimes (more often than not) get a full strength erection but whenever i try having sex
. I wake up with morning erections (not everytime) and they range from soft to hard. Is there anything i can do to fix this like stop masturbating, try relaxing and give it time? I would prefer not to have to see a doctor but i will if thats my only option.
