Yes mike, I do A-stretches, Upward Stretches, Bundled Stretches, & sort of a Reverse Modified A.....
(1) I pull my head outward with right hand (underhand grip).
(2) Then I ball up my left hand into a fist, & place it atop my cock, at the base.
(3) Now pull the penis against the fist, still going upward, so that it is "form-wrapped" around your fist.
(4) While pulling upward, also pivot your fist (thumb going in, toward stomach), getting further stretching leverage.
I get a mad freakin' stretch from these 4 moves.
I'm getting longer, for sure.
Some tips: Sit back in chair. Relax. Slow your breathing. Close your eyes. Concentrate as you S - T - R - E - T - C - H!!!
