Concerning about ED and Venous Leak

Hello there, recently I saw post from ‘sparkyx’ about defected valves in penis which lead to having problem with maintaining erection, or don’t having erection at all. (Read This First: Warning To Newbies)
This worries me because until now I thought the reason why I ejaculated without erection, was due masturbating too frequently/often for 10 years and that was even before learned about ‘jelqing’ and having surgery to remove phimosis.
While this can explain why I lost erection instantly after stopped stimulating, they’re other things to consideration like : overweight (over 50% my body’s weight is fat), as mentioned before masturbation, and penis injury due of being reckless (After phimosis injury I saw black string outstanding from foreskin [glans covered by foreskin], while I didn’t know how ‘stitches’ looks like, I thought it was string from cloth and I pulled it, it caused to dripping blood, but ignored after that reckless stunt, I have grain sized meat outstanding under meatus).

The question is, should I for this month try to : lost weight, stop masturbate and consume anything what can improve blood flow to check results?
Or should I immediately go visit urologist because even if these things mentioned above were causes, I could still have defected valves?

Thanks for helping and I’m sorry for bad English grammar, I’m even bad on my native language.

Yes

It took so long, but urologist send me to do CT scan of pelvic minor, and didn’t detect anything wrong.
The only thing I wonder is why scan pelvic minor instead of penis itself.

The test for valve functionality is a penile doppler ultrasound. Did your urologist discuss this test?

No, I don’t remember about that, x months ago he gave me recipe for tadalafil and something else (I forgot) . It worked way than I expected, it even increased 1.5cm in length.

Later at the beginning of this year when I told results and asked about cavernosometry, he gave me referral to CT scan of pelvic minor as a final test.

And when I gave him results last week, he told me that everything is fine and I should go to sexologist.

Assuming that everything is ok with penis, all I need to check if it’s due of obesity and sedentary lifestyle.
