I lie on my back with a raging boner looking at me. Then I take a t-shirt with one end in each hand. Then I slowly envelope my cock head at one end of the t-shirt and using it I cause the penis to pull away from my belly slightly. The good part-I slowly draw the t-shirt across my penis using various amounts of pressure and speed. I go slowly so it places an enormous feeling of tension upon my entire nervous system.
By varying the speed and pressure of the cloth upon my cockhead I can bring myself to exhaustion without climaxing. It is especially good if I start out with a very light tension on the cockhead. Moving the cloth eight to 10 inches across the cockhead slowly with just the barest amount of tension in this method has been known, all by itself, to bring me to an explosive orgasm.
What I see then is the clear shape of the outline of the head of my penis in position as the cloth travels ever so slowly over it. Being careful not to go fast or try even harder, just to keep a careful, light action, soon I see the cloth become moist!!
You quickly learn which parts of your penis are sensitive to which type and direction of cloth traveling over it. Be careful not to do it with too much tension because it will cause the penis to become de-sensitized.
Another method is to do it while wearing the t-shirt. Pull the bottom part of the t-shirt below your balls with one hand and then move your penis head up/and/or down across the fabric.
Sometimes I just move it up and pull the cloth away and move it up again and again until the spitting occurs. Other times I just slide in the opposite direction only.
I hope this message and technique I am sharing brings pleasure.
