Shaft grasper 

A shaft grasper is a woman inclined to holding on to the male organ with both hands. The shaft grasper is particularly obsessed with using the male sexual organ as some sort of symbolic status object. The longer she can hold on the better.
The shaft grasper is therefore not interested in providing relief of an ejaculatory matter, rather solely in maintaining the erect condition of the male organ and holding on for dear life. Shaft graspers are well known for gesturing their shaft grasping obsession with random objects like microphones, water bottles or other phallus like objects.
Shaft grasping is well known for causing blue balls.
