Whats the donut effect

Can someone explain to me what the donut effect is

Thanks

Click the button on the top that says “Search” and enter “donut effect”. Or, take a look at the bottom of this page and check out the “Similar Threads” section.

I believe it is when your shaft just below your head is swollen and often larger than the glans (like a donut) and it can be caused by PE. I had it in the beginning but balanced things out with other exercises.
