Here is my question, from my understanding of this is practically saying if you have a good erection, than exercises that help with lenght will help your overall results.

**The smooth muscle being the limit**

On the other end of the spectrum, you can have the smooth muscle "limit" larger than the tunica "limit." In this case:

- The smooth muscle is at or approaching the maximum the tunica can hold.
- So the smooth muscle is bulging into the tunica (think of it as pumping up a 15" inner tube inside a 14" tire).
- This in turn causes the penis to be extremely firm and hard when you have an erection, or a "rock-solid" erection.

Im a little confused with this and i would like to understand to figure out what future routine should i be implanting since at this point i feel like i understand "My Penis" more...
