I dont recall it, but that doesn't mean it isn't possible! and you have already shown that inducing priapism with PGE1 caused permanent size gains with your girth, not that I'm suggesting others do that, but we have a thread on it for those interested, be careful.
Being honest I never seen a cock that long, but one that thick yes. Both together would be the ultimate WOMD cock blaster that no adult entertainment slut could resist aye!
You could try pumping in a
cylinder that packs you, so it focuses on length. Do that with low pressure over many sets over say 1-2 hours, then get into a
hanger targeting the angles which hit the tuincae, so it would be OTS or SU.
Could only do that with very low fluid, and this is what will make up my own routine in the near future.
Throw into the mix several times a week something like expressive stretching, or if you can make it happen yourself, expressive
hanging to target inner penis.
The girth is much easy imho, length is a real fucking bitch! but that is what us men want, its always something great to have that length I think ... even though I have 7" girth I would feel better if I had a 10" long dick and 6" girth ... the women always loved the girth tbh but who cares what they like, its our body.
If you need help with a routine, let us know.
I chucked a few ideas your way from my own plan which will be starting in a few weeks.
O, nearly forgot ...I bet someone on the LPSG forums has a 13x7.5 (cwl)
