Big Vein suddenly appearing

I had my normal 15 warm-up period and then performed my 300 jelqs.
I had an adequate warm down period as well.

When I woke up today with my morning wood, I had a vein protruding from my base, up my shaft, then it turn to the under-side of my penis and then back “inside”

I don’t have a black and blue mark, or any blood spots only a slight discomfort.

What’s up with the vein pop?
Am I injured?

No. Your veins stay more pumped because they are carrying more blood.

Sounds like PE is working for you!

The same thing happened to me. Don’t get scared when you see a TON of veins show up. I can count 6 or so pretty hefty sized veins that weren’t on my dick last year but are now :)

Thanks for the heads up!

So if PE is working for me…can you explain the physiology?
A larger vein is appearing, which allows more blood and longer length?

If I continue Jelqing, then more veins will appear on the surface which allows more blood….
Am I using correct logic?

Also, is a vein “pop” an indication of locked in gains?
