I dont think its as horrible as you guys might imagine, the veins are not huge or bulging out to some extreme amount. My penis is very veiny by default, but its true that these veins are not visible normally, even when im fully erect. My guess is that it has to do with a lot of the "suction" being concentrated in that area and the veins get enlarged because of it. I found next to nothing on the internet about this issue, so maybe this is "normal" for my dick and its not a real concern (kinda like how a little edema after hanging is nothing to worry about), but still, I wont risk it.

I will try the water method tomorrow and if i still get the same issue i will stop PE for at least a few weeks.
