I can relate to the dripping. some times worse than others and typically for a 10 to 20 min period after urination,sometmiespecially on its own whenever. Never tried a clamp but can't imagine it would be comfortable. I am in transition and tired of having to stay in office until wet goes away. I have looked and there are numerous pad and sheath devices out there. Maybe even a belted product? Probably not much help but maybe some other options.
