My workouts suffer when I use ����. Problem is I get more into masturbating and forget about the exercises.
When I clear my mind, by visualizing what I am thinking about, written on a chalk board, and then visualize an eraser whiping the slate clean.
Then I'm ready and completely focused. Like 11x7, I use my own visualizations to produce an erection and really focus on what I want out of the session.
