PPP Causes - Girth Exercises?

I’m interested to find out what causes some guys to develop Pearly Penile Papules (PPP). A simple google search will give you tons of info on what this is if you’re not familiar. The medical field doesn’t know what some men have them and since they’re benign they don’t care to really find out. I’ve seen a few anecdotal theories on here and there on why they appear: cut/uncut, moisture on the glans, foreskin restoration, excessive masturbation, excessive sex, penis hygiene. I also came across some guys here saying that girth exercises make them worse. It seems like forcing extra blood into the head of the penis can make your PPP larger/more noticeable.

sam1966 - Whew!!! I only have Pearly Penile Papules.

Has anyone else noticed their PPP get worse or more noticeable after girth exercises?
