My foreskin is slightly painful to retract when erect, and oftentimes rolls back up after a few seconds. It feels very tight when I pull it back to expose my entire glans whilst erect, although it is manageable, 70% of the time, i d estimate. Ontop of this, my glans is quite sensitive to the touch and painful when it is exposed to things like water from the shower or a touch of decent pressure; is there anything I can do to combat these problems?
