It doesn’t stop growing.

I have a 13 inch pinish. I have a rare disease in which your penish don't stop growing, so I have to cut it time to time or else it becomes very hard for me to carry it around, so what I do is every Friday evening I cut my penish in 4-5 pieces untill it's in good size again, and I feed them to homeless people cause I'm a good person, although it grows back very fast but I have learned to live this way, I love my penish.
