Clamping with Binder Ring and engorged veins at the base

Hi there, it’s been a while since my last post, miss you fellow PE’ers here!

Now getting to the topic, I have been clamping with paper binder ring as in this picture:

As you can see it is perfectly round and don’t really follow the contour of penis as a regular wire-clamp does. But it is doing it’s job perfectly. I have placed the binder ring close to my base, just above the pubic fat. The only problem I have noticed is that I can feel a bunch of veins sticking out really prominently to the sides just below the spot (closer to base) of my binder ring is placed.

It’s not like regular bulging vein that I have seen all these years of clamping (not a regular clamper though). These vein bulge out prominently but only at the sides. It is accompanied by slight swelling as well. So should I ignore them or clamp slightly up in the shaft? Will there be any damage in the long run?
