Do you do exercises to strengthen your dong?

Do Keigels while driving about, to improve my cum shots. Hadn't considered doing fish weight pullups with my erection though. Lol

yes. i have midgets do chin-ups on it.

Yes I use something called the "block" regime!

BTW did you know that a Dong is a unit of currency of Vietnam?

Not sure what strengthening it means or why one might want to.
