I get "doughnut" effect when I masturbate
I have been getting the doughnut effect after my PE workouts. It used to appear more slowly with manual jelqing. But now it appears faster with the PJ device.
The fluid buildup is on the right side just below the head. It looks like there’s a squiggly, rigid snake under the skin. The doughnut is prominent and lasts for at least a couple days. I can massage it so it becomes flat but returns if I masturbate.
Does anyone know what this is and why it keeps coming back so easily?
