I’m uncut, but I keep my foreskin retracted all the time, and I’ve done so for years. I much prefer the way a cut cock looks, with the glans always exposed, and until I get circumcised, keeping my foreskin back is the next best thing.
When I first started retracting, my glans was hypersensitive to direct stimulation, almost painfully so. It made it difficult to keep my glans exposed for long. But I stuck with it, and gradually sensation in my glans changed and adapted. Now I barely notice when it rubs up against clothing, and direct stimulation during masturbation and sex feels really good. My glans also changed from being dark purple and sticky, to now being pale, dry, and silky, almost exactly like a cut cock.
Since indirect stimulation by gliding my foreskin over the glans no longer felt quite as nice, I now masturbate exclusively like a cut guy, keeping my foreskin held back tight, and either jerking the shaft, or stroking my glans and shaft with lube, which feels amazing!
