Here's a couple of glans enlargement exercises:
Mini-Jelqs:
Wrap one hand (or some fingers) around the lower half of your semi-erect penis. Wrap tight enough so that the semi-erection is maintained, but not so tight that you can't perform the exercise.
With your other hand; starting from the exposed mid-shaft, milk slowly towards the glans. Every 5-10 strokes, squeeze the shaft with only the head exposed for a count of five so that the swollen head is forced to expand even more.
Perform this routine before your regular
PE routine.
Of course, with practice, this supplemental routine should provide an extra stimulus for the glans to grow, if you feel you're lacking in that area.
This next exercise is known as the "ULI #3":
This advanced exercise is the brainchild of a veteran member of the PE Forums known as "Uli". This gentleman had attributed his girth of about 9 inches from using this exercise!
The Uli #3 is a method for gaining girth, particularly around the head.
You get a partial erection, grab your penis with the OK grip a couple of inches behind the head, and trap blood between where your fingers are holding and the head of your penis. Then you pull toward the head, forcing the blood toward the head, engorging the area to the max.
1. Start 80%/90% erection.
2. Perform a strong
kegel to get a full engorgement, then once kegel is completed grip the penis at the base with a ring-grip then slide SLOWLY towards your penis head (moving every drop of blood! important!!).
3. Once reached about 1/4 inch below the head, while still maintaining a strong grip perform a strong kegel.
4. Use your other hand to grip at the base while still maintaining a strong grip near the head trapping blood between the head and pubic bone and then.. and only then should you release your head-grip hand.
5. Repeat 7 to 10 times, then stop and slap your penis on your thighs to regain circulation. Rest and repeat the whole thing.
It is best to try for 5 minutes of performing this exercises. Work up to 10 or more minutes over the course of 6-8 weeks.
