Stretch Marks on Your Penis
I have what I can only describe as stretch marks on my penis. I have not gained excessive skin like some have described so I hope most of it is from size increase.
I do not want to bias anyone before I describe mine, so I would like to as three questions:
1. Do you have stretch marks on your penis?
2. If so do they run vertically (along your shaft) or do they run in a ring formation around your shaft?
3. Do you think the are caused by penis growth or skin growth.
