I've been PE'ing for about a week and a half now, doing the beginners routine. My EQ is good and I'm getting good expansion with my jelqs, but now I'm noticing this thing ring around the base of my penis where I begin my Jelq stroke. I can only feel it when I'm erect, but it feels like some spongy buildup on top of the erect penis. That area (base of penis) is tender to the touch, but its my understanding that is to be expected. I think it is because that's where I start my jelq stroke and squeeze the hardest there to trap the blood.

Is this normal, or am I doing something wrong?
