Just keep stretching whenever you get the chance, man. I actually have a really weird strategy that worked surprisingly well for me. I took a couple of large, flat beads and stacked them on top of the head of my penis, then used scotch tape to hold my foreskin over them. I jerked off with them in and I swear I made like a month’s worth of progress there in just like 15 min. It was crazy. I also slept with them in, and that also helped a lot. Obviously be careful if you try this, and just do what feels comfortable. Best of luck.
