Anyone Gained Length With Extender With Hard Septum?

Sorry I know this is in the wrong section but the forum rules won’t allow me to post it in the extender section.

Just wanting to know if anyone has gained any length using an extender with the steel cord/hard dorsal septum.

I have done p.e on and off for 12 years(mostly off). And last time I stopped was because I seemed unable to gain any length with this hard cord.

This time I came back for girth after never really training girth at all and wondered maybe I can still get some more length with this method.

I’m interested in any insight anyone can give on gaining length with the “steel cord”.

Thanks guys.

I dont know if you already know the thread, but igigi had the exact same problem:

In short, you will need to use therapeutic heat and stress relaxation and maybe other stuff and then you can definitely gain with a tough septum :-)
