I’ve always had a large glans that made a significant bulge in my foreskin. Pulling the foreskin back over it wasn’t as easy than it would have been if I’d had a narrow, tapered glans. And I find it impossible to pull it back when getting erection. I have just been able to see a bit of the top. After stretching a bit, I realized my glans is super sensitive and there is a lot of smegma buildup. It starts getting slightly painful, and the discomfort only increases if I try to fully pull it back behind my glans. As a result, after stroking in the morning, my foreskin becomes extremely sore and painful, and the next day dead skin will flake off. Is there anything I can do about this? Do I need an operation?
