I dont know if my problem would be classed ad ED anyway i will explain.
I can get erect but it will not stay on its own without stimulation so i guess this is not normal. Ive had this for many years and im now 27. But if im in a relaxed state for example half asleep in bed the erection will stay longer could this suggest maybe psychological problem? Say i was masturbating and stopped for 1 minute then it goes down, maybe its because im not concentrating anyway i doubt now if this will ever improve.
