If you cannot stretch your Tunica, how are girth gains possible?

So I hear every now and again from an individual that you cannot stretch your Tunica predominately. If that is the case, how are permanent girth gains even possible? Furthermore, if the Tunica can be stretched and then why would there be a cap on length gains?

It seems like it would act like most other tissues in the body but even if it didn’t you can pretty much stretch any live tissue and it will stretch and grow. Doctors can do this with bones even with large devices putting a lot of tension on the bone over long periods of time.

Any proof one way or another?

Pretty much everything you need to know regarding your question is in those two threads.

When you say “an” individual, do you mean literally just one person? Not sure why you would accept one person’s opinion over so many others. All you really need to do is get an eighty percent erection, make a good tight “okay” sign around the base, and squeeze the head a bit. Your tunica is being stretched. You could make a second “okay” sign closer to the head, but still near the base, overhand grip will work best, and then move it towards the head a half an inch, or just close your second and third fingers around your dick and give it a gentle squeeze. Tunica is being stretched, and you can feel it. Why wouldn’t you be able to stretch your tunica? Is it made of metal or stone? Of course not.

Rick, do you know how the doctors «stretch» bones ? The bones are not stretchable, so they cut or break the persons leg or arm, and then put in an extender device that very slowly is beeing adjusted, so that it opens the gap between the two ends of the bone, and widens it very slowly while the body tries to fill in the gap with new material - new bone.
