Masting

One who masts is somebody trying to force an erection by pumping blood into their penis via using their mind. This is reference when somebody is "full mast".
This excersize can help train a person (especially one with erectile dysfunction) to be able to gain and sustain a boner.

I woke up this morning and started masting to see if I could make my penis stand upright.
