Manko007's road to big dick land

I don’t know why I didn’t think of that. Great point

Another great idea… I use a kitchen thermometer. It is just asking for trouble.

A flexible probe would be perfect.

Look forward to that double test

I just ordered these:
Chinese Acupuncture Cupping Set, 12 Cups Professional Cupping Kit with Extension Tube for Body Massage and Pain Relief https://www.ama … /dp/B07Q8T19Q2/

I’m planning to fill them with epoxy to the inner tube to flatten the end. And try to pack each progressively as glans expand allowing more surface area and heavier weight over several sets.
Hopefully it works nicely. I got 6 leluv female sockets for standard pump gun as well. Just need to drill a small hole in each cup and epoxy to each.

Ill have 1.65, 1.77, 2.04, 2,36 and 2,75 diameter cups.

Im thinking i can already pack the1.65 phallosan xl cup i have. Then i can move on to 2.04 for precon to expand. And move back to 1.77 for hang as surface area will be saturated with expanded head.

So on and so forth until hopefully i can pack that 2.75 lol that will be an 8" or so head.

It can also synergize with my goal of 6.5" head, allow heavier vacuum hang sets, and therefore longer shaft.

Seems like a win win win situation.

Here is my newly made 5.3cm/ 2” vacuum cup. If I can fill this cup my head will be 6.5” and at 15hg pressure I should be able to hang 23.5lbs with lower risk of blisters. However its just theory.

So I got this blister 4 days ago. Real small. After hanging 10lbs for an hour. So my hanging is getting better. But in an effort to speed up healing today I put a silicon sleeve on to air it out as im uncut. And then it occured to me to put the old cock coil on. Well its awesome. I tied shoestring round my leg to keep it still as i walk and even went to the gym and did upper body. Didnt come off. The silicon sleeve has more friction than the hair tie wrap that Xeno endorses. The HTW never worked for me and took forever to adjust. The sleeve is easy to put on and reduces slippage.

Then it occured to me why not take it a step further and wear a vacuum cup at 5hg for hours and then put the cock coil over the sleeve. The cup stops the cock coil from going down and the cup increases your head size over time over many hours of tissue expansion, hopefully.

I was also thinking of having my head at 5hg over night. Once i deem it safe. If its at constant 6.5” size somethings got to give and cause growth right?

Anyway I cant wear the cup now cause of the darn blister so CC with sleeve only for now.

Man im excited to try these new things.

Im thinking after my sesshion once the freaking stars align that i can ads with this for hours. Even over night would be awesome.

Big dick island here I come.

One day ill be able to say big dick island here I am.

Real-time imaging of suction blistering in human skin using optical coherence tomography

So this study is about suction blisters.
There are some good graphs. At different pressures and temperatures when a blister starts, how fast it grows, and when it reaching steady state.

I can see from this that one can hang for only so much time given a pressure before the onset of a blister.
Minimizing temperature and minimizing hg should be a priority, to extend hang times, and decrease blister onset.

Decreasing temp from 35 to 21 has a great effect. Blister onset can be decreased from 2.5min onset to 10min later onset if surface area of suction is 21 degrees. This is the result of using 600mm hg of pressure which is about 23hg.

The lower the pressure there is an exponential increase in blister onset times.

I am thinking to use an icepack sort of thing while I hang on the end of the cup to cool the surface at vacuum.

I want to do a personal log of hang times and compile a chart of hanging times before blister onsets at given weights. This should allow me to know when to stop hanging before a blister.

It can be a useful guide for others as well.

Since I plan on using different cup sizes, here is what I could theoretically hang:

D IN D CM CIRCUM. FORCE lb kg
1.65 4.2 5.18 12.83 5.83
1.73 4.4 5.44 14.14 6.43
1.97 5 6.18 18.26 8.30
2.09 5.3 6.56 20.52 9.33
2.17 5.5 6.80 22.10 10.04
2.32 5.9 7.30 25.43 11.56
2.36 6 7.42 26.30 11.95

at psi 6 (12hg)

So far I am at 1.65. I should be able to hang 12.82lbs comfortably before suction gives. Once suction gives, this causes a small dead space, where the blister starts to form, at a given pressure which is probably much higher than 12hg, as the space is small and the pull increases it.

I hung 5kg last time for about 1hr before a blister set it, so it can be confirmed that the theory is sort of practical.

Ideally I’d want to reach 2". That way I can reach 9kg for at least a couple 20min sets. And for longer sets I can hang half that, 4.5kg for twice the time or more, as lower chance of creating dead space.

Back in business. Two separate heating and cooling cycles produced. Two channel thermometer used for measuring urethral temperatures.

Detailed analysis coming later on my log.

Hear is a sneak peak on results.

Nice! Interesting results. Seems quite similar to mine.

It looks like there was a lot more variability in your data. You could do a summary statistics of 0 to 15min to compare with mine and see if indeed it is.

Also, interesting how your temp at 10min into cool down was 98 degrees, but starting is lower like 88 to 90. Same was for me. Seems like temp really just plateaus on the way down at 98 at t10 despite lower starting temps. Perhaps a longer cool down to the tune of 15 to 20min would be in order.

Look forward to the detailed analysis.

These statistics suggest the inefficiency of the 1.6 w/ cm^2.

Comparing to your data 0-15 min heating fail to achieve the heating rate achieved with 2.0 w/cm^2
Once the therapeutic temperatures are achieved it looks a little better though.

There are two major differences between our studies, your transducer was applied dorsally, and mine was ventrally. So the effect with 1 MHz at least with your approach was greater on the urethral probe than mine.

This cooldown plateau could be simply caused by accelerated bloodflow by the heat and ultrasound. It can take quite some time to stabilize back to normal. The temperature is anyway at physiological level more or less.

Definitely less variability and greater mean, median with my device.

There should be a test done to address the second difference. I can’t apply it ventrally as my probe is stiff. Maybe if I get a flexible one some day.

It’s definitely enlightening to see the results though. Quite a difference. Although your gains are evidence of 1.6 w 1mhz being enough, so that is the silver lining to this.

At $650 machine vs. $120 machine, the price difference is higher than the marginal benefit it seems. And probably even less so if second difference shows more similarity.

I surely can apply the transducer dorsally, but I don´t know if I volunteer. This line of science hurts when pissing.

In fact I forgot to write the actual second major difference. You had only one thermometer probe in.

Yup, drink lots of water. Add some baking soda if you have any.

That is a big difference. And the third difference is you moved from T1 to T2 probes a lot. I didn’t realize this. So I can’t say with much confidence that my machine is better anymore.

I would say instead of getting a $650 machine. Get 2 or 3 $120 US machines and attach them together. That will be the best.

That WILL be the best. I was pondering If should buy better machine. I don´t anymore.

If I were to run this one doubled it would have 1.6 w/ cm^2. At 8 cm^2 area.
I already know that with the minimum of 6 cm distance center to center they are not interfering each others.

Even if they were closer than 6cm, would that be a problem? Do you think the sound waves could collide in some way to cause problems?
