Not that it is of any world crushing concern (but I did spend some time on it)
The best method (to enlarge the penis) is to purchase a good high quality rubber tubing. Tie a loop in one end and slip your foot into the loop before you put on you clothes (which foot will be determined by which way you hang). Now, while seated, take the other end and secure it just above (or below, depending upon your point of view) the glans penis, firmly tightening it until the glans begins to change color. The penis corona will help hold the tubing in place, just as it does with your hand. Now get dressed and stand up. If you have fastened the band correctly you will feel a constant downward pressure on your penis due to the stretch of the tubing.
Now, jog in place for a few seconds. Note how each step increases the tension. If this happens, perfect, you have just installed the penile stretcher correctly and every step you take and every time you stand you will be lengthening your male member and best of all, since it is secured under your clothing, no one will be the wiser.
Note, as your penis lengthens, you will have to shorten the band each time.
Also, once the head of your penis is below your knee, this method is no longer effective because no stretching of the band occurs with movement.
If additional length is required then I recommend the following method (Note: this method is only effective for those peni over 59 cm in length.) which can be done both at home and at work in certain instances: Several times a day, while seated in your chair (a hardback, dining room chair is best), take your penis in hands and, while maintaining an erect posture, place the head of your penis in your mouth, holding it firmly behind the glans utilizing your upper and lower incisors. Now, with penis securely in place, lean your head backwards as far as you can. You will immediately begin to feel a tightening stretch to your penis and in a few weeks you will notice additional inches in your penile length. I recommend starting out with 1 set of 10 reps and increasing the sets over a period of several weeks.
In time you will note that you are no longer getting any stretch and when you do, it can be compensated for by inserting more into your mouth, grasping lower down the shaft, rigidly with you teeth. It is worth noting here that at this point some men have problems with their gag reflex kicking in. If this happens to you, do not be concerned, this reflex can be overcome; it is not hard, it just takes more practice so keep it up.
Hope this helps, be sure to check back in and let us know.
