I have been using the [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]SG[/words] + [words=http://TLCTugger.com/MOS]VLC[/words] for almost 3 weeks now. Have gotten with what looks to be some stretchmarks on my penis in a few areas. Is this normal? Is this a sign i am stretching too hard? i dont feel any pain, only the pain from the skin portion where it's stretching.
