Stretch Marks from manual stretches
So I’ve been doing a lot of manual stretches and have been pulling hard on my penis and skin. I can clearly see little circular around the shaft stretch marks forming. I’m wondering if I’m doing too much. I grasp the skin low and pull which gives my skin a very hard stretch (an gives my penis a very good stretch too). I don’t want the stretch marks to get bigger. Are you more susceptible to getting stretch marks by doing manual stretches than by doing jelqs or hanging?
