Its complicated.
After I discovered I had pfs I supplemented ginko+acetyl carnitin, added maca-tribulus shortly after. That did something very weird, I had very often spontaneous erections which is by the way not a good thing, because I got them without even being aroused. During this period I was about 70% pre pfs (which is hard to quess), it wasnt great, but quite good I was able to have sex and it was somewhat acceptable. Then I got worse and I stopped supplementing, started again, got better and so on.
Then I switched to another tribulus, which made me feel like shit again sexual wise, and I stopped. After one week of not taking anything I got better, again feeling even the desire to fuck a woman who was before me in the waiting line. I had very strong hard erections, but numbness was still severe, felt very weird. Then I got worse again.
Then I took betaine, Vit A and Choline, Betaine and I got better. Meaning I got normal erection, almost no numbness, and good sensation, but still low mental libido meaning I only get aroused if I touch myself or if I getting touched by a female. Increased semen volume too, but like water.
