Shouldn't you use it exactly where the leak is?
If it is in the pelvis, this device will not do anything

I started with HF which then turned into LF and I've had it for years
All symptoms match

Symptoms indicate venous leakage, do penile doppler

I've only heard positive things about embolization, but never about ligation

No but I think it might be something with the pelvic floor because I feel like the muscles there are weirdly weak and I remember it wasn't like that before

I never have full erections, only partial ones, and not always

My penis behaves the same, slowly descending and bouncing, which shows that the blood is not trapped

You can try butcher's broom and daflon
I read somewhere that it can help with erection and venous problems

It may or may not help

It is stiff on the sides and flat, but the spongy body is soft
