Some days ago I restarted my newbie routine, but I give up after three days of PE, because I noticed that my upper shaft and the head (only the skin covering the glans. I’m not circumcised) have a color tending to brown. It wasn’t so evident, I could notice it only when flaccid but I decided to stop. Fortunately after some days it fades away. I think It depends on my stretching grip, and for this reason I want to use something to make the grip easy and not create skin soreness. Did anyone of you have my experience. What do you suggest?
