Pumping vs clamping
I have been doing PE for a few months. I am contemplating doing either pumping or clamping. Since they both cause blood flow to the penis, I only want to do one of them. Pumping seems to be safer and easier to control. I am a bit freaked out by pictures of clamping. The discoloration is a bit too much for me. (I understand the discoloration is only temporarily.) Is pumping a suitable replacement for clamping? Or they are different? Do they antagonize each other?
