You can make an extender to be placed under the foreskin when cross-taping to keep it stretched. The drawback of this method is the discomfort. By the time you might consider using an extender, your glans penis will have become used to being protected for well over a year and objects pressed against it will be difficult to tolerate. This can somewhat be alleviated by ensuring the extender is perfectly fitted to the glans penis. In the example shown, a plaster cast has been made of the penis and a silicone extender was molded from it.
Although non-surgical foreskin restoration has been practiced since antiquity and modern tape-based techniques like the method described here have been successfully implemented for over twenty years, the information on this website should not be construed to be medical advice. Consult with your physician if you have any questions, concerns, or problems.
