Well, that was a very elaborate answer!
Thanks! Just wondering if there'd be any pictures of those two techniques? My search hasn't yielded anything yet.
No photos of this stuff, as far as I'm aware of, outside of water pumping. Really, it's not complicated enough to need photos.
An extra bit of info on the condom pumping - this method comes from the PE world. The idea is to put more focus on tunica expansion. You want to go a condom size smaller than you would normally wear to simulate a tighter skin. Because of the tightness, it prevents fluid build-up and supposedly gives better results in the long-run for girth enhancement. I don't do this regularly enough to test how true it is but you can read more about it in places like PEGym, Thundersplace and MattersofSize.
Also, as the others have stated, don't overpump. Meaning, don't pump too long or with too much pressure. Personally, I prefer to stay between 5 and 7 HG for 15 minutes. I only go below 5 HG if I feel like wasting an 45 minutes pumping - since it's part of my PE routine that is usually just far too long.
Also, ew. I noticed I used 'then' instead of 'than' earlier. I feel dirty...
