Penis Pump Cylinders

Hi…I have 1.75 and 2 inch cylinders from leluv. Currenly using the 1.75 and packing the base and still below glans not packed. It seems the foreskin making difficult to get enough vacuum to the shaft. Coz i just retract partially and then enter tube. Is it ok to enter tube with foreskin not retracted?

Thanks

Hi guys… Today I got plenty of time to do the PE ( other days limited time ). I started with 5 minutes warm up by hot cloth. Then 20 mins stretching followed by 5 minutes jelqing. After jelqing entered in to the 1.75 cylinder, used 4hg pressure. Release the pressure in every 5 minutes and then 30 seconds idle x 3 time ie 15 minutes. I did milking and kegels most time while in tube. I can see the tube is almost packed. After 15 minutes i take out of cylinder, massage 5 minutes jelqs. Then enter in to the tube again and i noticed it is not packing easly for the second session. I did another 15 minutes and every 5 mins 30 seconds reduce vacuum to 0-1 and finally packed the tube.

What is is my concern can i continue the pumping after that first 15 minutes by every 5 minutes 30 seconds break till reach 5 x 6 times ie 30 minutes. Then do some massages and jelqing 5 mins and warm down. I use hot wrap throughout the session.

Thanks

Best way to find out is to give it a try and monitor your results while you proceed. If you get negative feedback either during or after make adjustments to cut back.

I measured my base girth yesterday, and I have 12,4 cm(~4.9 inch) at the base. But If I buy a 1.75 inch tube, I’ll have an available free space of 0.23 cm, due to the negative pressure, for sure I’m going to fill the available space, But my main goal is girth, should I go for a 2 inch cylinder?

First, I don’t know why you didn’t post this in the Selecting Your Cylinder Size thread that is listed in the first post of the Really Good Pumping Threads.

Now, that thread recommends for your base girth, the 1.75 cylinder is right for you. You could try a larger size, but you might have trouble with your balls getting sucked into the cylinder. What is your erect girth at the middle of your cock?

Sorry, I was reading that thread, but I had many browser tabs open, and I ended up posting in the wrong one.

My erect girth at the middle is almost the same, if possible, delete my posts to keep the thread in context, sorry.

I would still recommend the 1.75”. Your choice if you want to try the 2.0”.

Don’t worry about your post, but we don’t delete them.

Very happy with my ib-8080 breast enlargement machine that was bought a few years ago.

It has a pump pressure of about -45 cmHG and different pump speeds 0.1 - 0.3 - 0.5 - 0.8 - 1.1 - 1.5 - 2 - 2.5 - 3 - 3.5 -4 - 5 sec. In and out intervals as well as pre-programmed intervals.

For example, you can set it to in 1.5 and out 0.5, the pressure will then be about -30 cmHG.
My own setting when pumping with a minimum of 70-90% EP for about 5-10min.
I take out my P and jerks / jelqing it up to 70-90% EP 3-5 times repetitions.

It should be mentioned that I use base oil and essential oils as a lubricant to get more blood before pumping.
After the session, jerking / jelqing up my P to 100%.

Do you want to know more?
Just let me know :-)

To anyone reading that, be aware that a lot of essential oils will seriously and quickly damage a lot of types of plastic, including acrylic pumping cylinders.

I have a few questions about the Leluv pump.
I have been using the Bathmate for about 6 months, but I’m tired of getting the donut because of not using the right amount of pressure. I went to the Leluv site and found the one I am considering purchasing. I don’t know if I’m allowed to post links. If I am, I’ll edit this post to include it. Its called Tyro Penis Pump with MASTER GAUGE 2.4 Inch Diameter Cylinder. Now for the questions.

1. I read that I should lubricate it before use. Can I use Coconut oil for this? If not, what is the best lubricant to use?
2 I see that it comes with a sleeve. Should I use this? I don’t use it on the Bathmate and I get a better seal without it.
3. I’ve read on here, that I should be starting out at 5hg, What is the maximum hg I should use it, after months of becoming use to it, 10hg?
4. Finally, what is the best way to clean it and remove the lubricant from it after use?

Thanks so much for any help!

It is a pistol style vac pump; I don’t know anything about this particular pump but looks ok. A 2.4” diameter cylinder is pretty large, but the selection of sizes is limited now.

1) I use coconut oil to lube my balls and base of my dick. Shaving pubes from cylinder contact area will yield a better seal.
2) your choice. Try it and decide if you like it or not.
3) Every guy responds to vacuum pressure differently. Ease into it and watch for warning signs like petecia, blisters, numbness. Higher vac pressures are more commonly used by guys trying tombreak a plateau. They generaly have been pumping for years, not months.
4) Soap and water. Harsh chemicals including alcohol can damage the cylinder and lead to cracking. I ruined a tube cleaning with alcohol.

@32quarters Thanks for replying. So I just went and measured my girth erect and it came out to be 4 3/4”. That tube says its only 2 1/4” in diameter. So that means I won’t fit in that, which doesn’t seem right. I was using the x30 in the Bathmate, which is their smallest pump. So either I’m not doing this right or I don’t understand Leluv’s measurements. I measured in the middle of my dick. I’m guessing they are measuring from the center out, which still means I might be cutting it close. I suck at math.

You are confusing girth (circumference) and diameter. The equation to calculate girth is:
Note that Π (Pi) is a mathematical constant which is 3.14.

Girth = Diameter x Pi
Or
Diameter = Girth/Pi

In your case, a girth of 4.75” yields a diameter of 1.51” —-> Diameter = 4.75/3.14 or D = 1.51”

A cylinder with diameter of 2.25” will fit girth of 7.1” —-> Girth = 2.25 x 3.14 or G = 7.1”

So a 2.25” cylinder will work for you but the best fit for you would be a cylinder as close to but larger than 1.51”, which is a 1.75” cylinder. A 1.5” cylinder would be too tight for you.

More math for those interested:

You may also have seen the equation for circumference (girth) shown with radius (r) instead of Diameter (D). At Thunders we more commonly talk about girth instead of circumference and diameter instead of radius, so I’m showing the equations with the more common variables.

Girth = 2Πr or 2 Pi r
Since the radius is half of the diameter or diameter is twice the radius (2r = D) we can substitute and restate the equation for diameter instead of radius:

Girth = DxPi

To best calculate the cylinder fit you need to measure the largest part of your dick/glans. If another section of your dick is larger than 4.75” you need to size for that larger area.

A 1.75” tube will fit a girth of 5.5”.
