Every man has the septum; it’s an anatomical part of the penis; it’s not optional and it has the important function of protecting crucial nerves. But not all men have the same type of septum/dorsal thickening. Some are more pronounced, vary in length and elasticity. That’s when the limiting question comes into play. I’ve read all kinds of suggestions here but all you need to do really to figure out what kind of septum you have is compare two basic measurements: BPFSL and BPEL. Don’t include the head in the measurement as it is not affected by the septum and therefore irrelevant (and even misleading if included in measurement). We should probably have a poll on this. For instance my stretched length is 0.5” longer than my erect length which basically means that I can still grow another 0.5” before I reach the limit set by the septum. I call this a moderate septum problem. If septum stays the same I may still grow length after this but it would most likely result in a curved penis, since straight lengthening is limited. I speculate that for guys who report “no cord” the difference between flaccid stretched and erect is higher, probably at least 1”. Conversely, guys with a very stubborn septum would probably see no difference between the two measurements or even a slightly negative one (shorter flaccid stretched). I’d like to see some statistics of course.
I’ve started using V-stretches after a strong heating session to make the cord more flexible. My PE routine is jelqing only. I must say, however, that I gained somewhere between 0.5-1” in six months and I have always had the “steel cord” issue. Although the measurement described above is a relatively recent concern - so I cannot compare to what I started with - I must conclude that the septum has already become more flexible through jelqing or it simply developed larger cells to accommodate growth. Let’s not forget that jelqing affects the corpora cavernosa but for the penis to grow in length all the other anatomical parts of the penis need to agree, including the septum. Otherwise I cannot account for my length gains and for the fact that I still have a 0.5” margin left in the septum.
