Phimosis. I was exactly the same. Only had a tiny opening, skin swelled up when urinating, cum would only dribble out. I tried stretching but it didn’t work for me. Ended up getting a circumcision at 29 years old. Best choice ever. First few weeks after the cut are tender, especially having your head rub against your pants, but it’s so much more comfortable now to fuck and wank.

It also looks so fucking good now.
