I've achieved a gain!

While I was erect the other day and looking at porn, I squeezed my penis and sort of masturbated the shaft all the way up to the head without touching it so as not to reach ejaculation, later in the day I noticed my cock was a lot thicker so I decided to measure, and sure enough I'd gained at least a 1/4 inch in girth in the first session. I'll post updates as I continue this new exercise and let you all know if my gain was only temporary. Please fill me in if anybody else has tried this and the results they found!

i think thats called "jelqing"

there are many here who do that and i bet they can fill you in on the details

well i've learned all about jelqing from this site but its not done while erect and its done much slower, so I'm quite certain there are some big differences from what I did and jelqing but maybe not.

difference in technique maybe. the purpose of jelqing is to force blood up the shaft and into the glans by squeezing the penis and it sounds like thats what you were doing.

lol, Sounds more like swelling to me.
Did you maintain over a number of days?

so far at least 24 hours, I'll keep you posted how long it lasts. I'm guessing it will subside eventually but it appears to be an easy way to pump it up!

Supposedly, if you keep it up, those temporary gains become permanant. I don't have the patience or self-discipline for it. :p But congratulations nonetheless!

Sure, jelqing IS done while erect for girth gains. Flaccid jelqing won't bring you gains in girth.

UPDATE: It's been about a week and I'm holding at a quarter of an inch gained. I don't do the exercise quite everyday as to not overdo it. I have noticed CONSIDERABLE flaccid size gained too! This has been the most noticeable change and it has certainly given me some confidence. I'll keep at it and continue to update.
