Swell-in pumpin

Great sight really appreciate if it works. I just got into this new pe programme that combines jelqin and pumping, but lately I have noticed that when I pump I have this enormous swellin along the bottom part of my dick. It is largest at the bottom and becomes thinner as it goes up kinda like a pyramid. After pumping there is a residue. I think it is the urethra or something. Some advice pliz.

It’s hard to comment when you don’t describe what you are doing. What pressure are you using and how long do you pump for? Do you use lubrication to seal the base of your cock? This residue, is it fluid coming out of your urethra?
