Hi Doctor. My Name Is Ken. English Is Not My

Hi doctor. My name is Ken. English is not my 1st language so sorry for my poor English. I am a 21 year old virgin and I have problem achieving erection and I think I have venous leak. I started masturbating with porn since I was 15. My erection quality has been very inconsistent since then. I rarely have random and spontaneous boners. But I can get hard with porn and with my hand squeezing it. My penis mysteriously stopped working on 13 Sept when I was trying to mmasturbate. Iwent to the doctor and checked my blood pressure and said I don't have hyperextension. I also don't have diabetes. The doctor said it's psychological but it was just his guess. I then stopped watching porn and masturbating. Its been 50 days now. I saw improvements in the 1st 20 days as I gradually regained my ability to achieve full erection. But after that I don't feel any improvement at all.

Here's my symptoms:
I can get 100% full hard when I am laying on my bed but I need to use my hand to squeeze it. Once I get hard I can maintain it for a couple of minutes without physical stimulation but my erection quality is very inconsistent so sometimes it would only get 60 to 70% hard.

I can sometimes achieve pretty hard erection but I have to use my hand to maintain it. Without physical stimulation it quickly dies.

Achieving erection while standing is very difficult for me.

Also after I achieve hard erection. I cannot get another erection immediately. It's like my penis got tired.

No random boners or spontaneous erections.

I''ve had really rock hard morning erection for 3 consecutive days but it get soft quickly after I woke up. Dead penis during the day.

After I ejaculate it often takes a couple of hours before I can erect again.

I don't think it's psychological because I am anxious because of the situation, not the other way around. Also I sometimes can achieve full erection when I am nervous but sometimes I can't achieve erection even when I am relaxed.

My appointment with the urologist is in next month so I kinda worried right now. I checked the symptoms of venous leak and I think I have all those symptoms. Do I have venous leak? Is it treatable? Thanks doctor.
