Stretch Mark's On Penis From Extender

I’ve been using the Phallosan Forte since July 2019, and starting in January 2020, I added an X4 Extender to my routine. Because of my current routine, I’ve only been able to use the X4 for a maximum of 1.5 hours, almost daily.

I noticed 4 bands of stretch marks towards the base of my penis when looking down at it. They are not huge or discolored, but I would like to try and get rid of them if I can

Do the stretch Marks mean the tension was too high from the Extender? Also, are there ways of preventing future stretch marks while PEing, or are they an unavoidable side effect? Should I take a month off of PE to try and get the stretch marks to disappear with treatment? I don’t want to make my penis ugly, especially since I think aesthetically, it’s always been a nice penis. I just want it to be bigger.

I posted about this in the injury forum but got no response- Does anyone have experience with a Derma Roller on their penis for stretch marks? Thank you!

I’ve been using my X4 for almost a year and have had some good gains. I never had stretch marks but I definitely had more foreskin which is a plus since I’m circumcised.

I have stretch marks from jelqing more than ten years ago. I don’t really worry about it, though I think it indicates to people that I have done PE. They do seem to fade over time.

Interestingly, it doesn’t seem like penis pumping causes the ring like stretch marks that jelqing does. I haven’t noticed any new ring stretch marks while pumping and light hanging.

Over pumping, particularly when combined with sliding the tube back and forth while pumping (I think it’s called “milking the tube”) can cause vertical stretch marks just behind the glands, on the side that does not face you. Edema seems to significantly weaken skin integrity.

Aggressive clamping can cause these same kinds of stretch marks as well as a kind of deformation of the glans where the space on the underside of the glans, below the urethra opening where you see a sort of seam, separates more.

I’m speaking based on my own experience as a circumcised individual. I think that the circumcision scar plays a role in forming the vertical stretch marks on the shaft since they only seem to appear near or on the circumcision scar. There is a certain amount of variability in the shape of the glans, so that probably plays a role in whether or not you might get glans deformation from aggressive clamping.
