Gains Between Glans and Shaft?

Hello Thunder’s,

I was wondering if anyone has found solid literature/threads/posts about methods to gain size between the upper shaft and glans.

Most threads speak about pulling out the inner penis or all around stretching throughout the entire penis (tunica etc) for gains. But what about the area between your glans and shaft?

When I first started you used a cheap extender from ebay to gain ~0.3 inches in a month or 2 and I stopped after it ruined my erection quality for the next month. However, I noticed this light-skinned scar tissue from the extender between the upper shaft and glans.

So my question is, did this part of my penis specifically grow? (And if so how can I actively target it!) Or is it just skin forming? Why doesn’t other parts of stretched penis look like this?

If you google circumcision scar, that’s exactly what it looks like, and I have seen porn stars with the same scar that varies between 1-2+ inches.. And I now have the same scar ever since that incident.. So what is it? Is it beneficial? Is it just skin tearing? Or is it creating new penis tissue from under the glans? Should I aim to keep opening up this tear or should I not pull from the glans?

Any solid advice/info/literature would be very helpful, thank you!
