Derma Roller On Penis For Stretch Mark's

I’ve read a couple threads on here about people who’ve used a derma roller to help with stretch marks on their bodies, but has anyone specifically used a derma roller on their Penis to treat stretch marks?

If so, what size needles did you use and did it help with the stretch marks? How was the overall experience?

Does anyone know if stretch marks will get worse when doing PE? And final question, are you more likely to get stretch marks from certain devices more than others (for example, are extenders more likely to cause stretch marks over hanging?)

Thanks!

Stretch marks would likely get worse when doing PE as by the very nature of the exercises you are stretching tissue.

I would imagine that extenders could cause more stretch marks than other forms of exercise, but I am sure it varies from person-to-person and depends on the intensity with which you are exercising
