We’ve tried chastity on and off now for awhile. Every time we start up again, he keeps getting these uncomfortable, almost painful bumps on the shaft of his penis. These pop up when I take him out of the cage and he gets hard. They go away if he cums, but continue to come back for a few days afterwards too. We’ve tried 4 or 5 different cages and it hasn’t seemed to make much of a difference. Has anyone else had this problem? Is this something we should be concerned with?
