PA5000 discussion

I picked up a PA5K last week and have been wearing it continuously for seven days. It feels very comfortable with no pain involved. The sensation is amazing—having what feels like an “almost erection” but being unable to relieve myself by stroking. Sure, the key design isn’t 100% secure. I suspect there are others just like it out there. It does get a bit smelly… fluids can gather in the lock area and effectively “marinate”. Lastly, those vent slats. I need to fill them! Could someone share a method for plugging the vents without adding too much bulk? Which epoxy or putty works best?
