Aloha from Hawaii
I am a surfer and windsurfer who already had lenght adn girth to start with and that was a curse as gains were harder.
I started at 8 inches with about 6 circum... and not much gain till I tried pumps.

You had questions about pumps and I beleive they are more permanent than any other technique
Use your first one (tube) for length and the wider one for girth if you use a tube much larger than your diameter you get enormous girth results I mean gigantic girth As far as I am concerned pumps are the ONLY way tom get girth and alll fast gains.

pumps=fast gains and it only takes a tiny bit of stimulation to get erections and girth once you get these gains.
I dont check the forum often

Pumps will astound you if you get a good one.
the reason you want a wide tube and a longer tube with narrow diameter is one each for length and one for girth.

But always always stop before you get too much "pain " if you get any discoloration it waill go away just stop for a few days.
Pumps are the best way to get fast gains and it only takes a tiny bit of stimulation to get erections and girth once you egt these gains.
