Have been PEing very consistently (4 on/3 off or 5on/2off) for the past 3 months on JP90. I've made some gains but have also noticed a vein that has formed on the underside of my shaft. It has gotten a lot more prominent since starting PE, giving the bottom side of the shaft an increased vascular look. It is also present when flaccid.

It's not painful at all. My EQ and erections have been great since starting, and I usually take 10-15 minutes to warm up with a rice sock before every PE session.

Its hardness is similar to the veins that run on the top of my hands. I think the vein is slowly branching out as well.

Is this something that I should be worried about, or just a normal symptom of PE?
