Vacuum Pumping 101

Hello friends, I have been pumping for about 6 months with good gains, especially in girth, my first pump was a pump with a vacuum gauge built into the cylinder, it’s cheap and the vacuum gauge is not of great quality, the reading is in mmHg, but it worked well for me, but I decided to take the advice of a very knowledgeable and experienced friend on this forum and buy a brake bleed kit and make a custom pump that only has to change cylinders and not all the pump. So far so good, but the problem is, I tried to follow the advice of many here who say that it’s better to never go above 4-5 inHg, but with the old pump I felt that it was not enough pressure, with 5 inHg I felt a pressure very low, maybe at the level of expansion a little lower than that of a normal erection, so I started using a minimum of 6 inHg and a maximum of 8, and it worked for me, it was always comfortable for me and I never had any problems, but when my brake bleed kit arrived I made a comparison with the old pump and the pressure reading on the brake bleeder is half, that is, while on the old pump the reading is 6 inHg, on the brake bleeder is of 3inHg, now I don’t know if I was always pumping with 3-4inHg or with the brake bleeder a pressure of 5inHg would be excessive, so I wonder, which of the two readings is wrong? Is there a way to test the vacuum gauges? Should I continue pumping according to the previous reading? Or should I test at about 4inHg with the brake bleeder reading?

I thank you very much for helping me and sorry for the grammatical or / and writing errors that I may have, English is not my first language.

Hi…I think your old gauge is not accurate that is why you feel comfort at 6 -8 hg. The new gauge you bought is accurate and in that you can do 3 -5 hg range and feel how it is. Later you can try beyond 5 hg if you don’t feel expansion. Hope this helps

Hello everyone. I am new to pumping and up until this point I only just started stretching with an extender for about 5 months and already saw big improvements of about 1,5cm. I bought a pump with a gauge and altho I never got past 5 inHg I still feel a bit uncomfortable. The sensation is not pain per say but it’s like my skin is stretching too much and it leaves me uneasy all while not even reaching my full erect length. Today I had my second session and as soon as I removed my penis from the tube it was a bit dark purplish but it came back to normal color in just a few seconds. The thing that caught my attention the most tho is that I had some red spots on the shaft of the penis. Not many and not super dark spots but a few. Is that supposed to be normal? I didn’t use much pressure and I didn’t even reach full erection length, am I doing something wrong? By the way, I did a 10 min session right after extending for 1h30m and that’s it.

Much appreciated for any help.

Holy Schnikes.. This is a long and information packed thread.

Hello everyone. I’ve been pumping for about a week, taking a day off in-between pump days.

The pump I purchased was from LA Pump and I followed the measuring advice and video on the page.

I am facing 2 concerns and it’s probably posted on the millions of threads, but even after doing a search I couldn’t find the correct ones that addresses my concerns.

My first concern is regarding ejaculation while literally putting my penis inside the cylinder. I can’t put my penis in completely erect because as soon as my glans touches the inside of the cylinder I almost ejaculate. Now, I don’t have premature ejaculation, so I have no idea what this is other than a new psychological dopamine release based on something nonsexual. Any thoughts or advice?

The second issue is understanding when I should upgrade to a bigger size cylinder?
I may have gotten the wrong size to begin with and have found that within this past week that I’ve had it, I’ve already feeling that I’m too large in circumference. In fact, I can’t ever insert my penis when I’m completely hard because I’m already too large for it (the glans). This was not an issue when I first got it so I don’t know if maybe I wasn’t completely as hard as I could have been the first time I tried it and now I am. So I have to wait until I’m a little bit but not too soft.

Maybe the latter has more to do with my former issue. But I just don’t know enough.

What about LeLuv?

Some guys are more sensitive to vacuum pressure than others, and you seem to be a little more sensitive to -5inHg starting out. You need to get your penis conditioned to pumping and start with a -3 or -4inHg until you do. Red spots (petecia) is another indicator that you are not accustomed to -5inHg. The skin stretching an be alleviated by applying your choice of lube or lotion prior to goingi to the tube.

I have no advice on your ejaculation issue; yours is the first like this that I am aware of.

If your glans is touching 360° while in the tube it is likely preventing the full vacuum from reaching your shaft. If this is the case you probably want to get a larger cylinder/tube. Measure the largest area of your penis when sizing for a new cylinder.

If your glans is only making slight contact then just keep it well lubed so it will slide up the side when it engorges from the vacuum. I have an upward curve and my glans always makes contact.

Can you be more specific with your question?

LeLuv is the best as far as i know for America and Canada customers, but there are some in Aliexpress way cheaper and the same quality, just read reviews and remember to look for one that has the Hg pression level on it cause you dont want to go more than 7Hg

LeLuv is a provider of good quality vacuum cylinders at decent prices. There are several other companies who also have good quality cylinders, some with good prices and others at higher price points.

I have multiple LeLuv cylinders.

Hi,

I’m quite new to pumping and have made some gains with my hanging routine. I had an electronic pump without a gauge and it ended in tears after a blister developed on my glands. So I reset and bought a manual one with a gauge so I can control the vacuum better. Any suggestions for the first month?

Keep under -5 hg and slowly increase set times from a few minutes a few times a day to your limits, which you will discover as your practice.

Use heat! Go in warm and keep it warm for 3/4 of the time your in. Let it cool off at the end. Be careful not to burn anything.

Thanks! I really appreciate the advice and have started slow. I had a good week and will progress with more sessions in the next couple of weeks. The immediate girth increase just looks great, but I’m sure that over time it would remain permanently.

Hey everyone. I just joined here, but I’m not a newbie to PE. I used to be one Matters of Size back when I was in college (around 2011 or so) and experiemented mostly with girth work. I had some success, gained a little over .25” in girth. But I was an overzealous idiot, and I have small dots on the underside of my penis from where I burst some capillaries trying to rush gains. But I’ve been out of the game for a while, except for a few weeks of jelqing here and there. After hearing Leo Rex and Susan Bratton talk about the legitimacy and benefits of pumping, I decided to give it a go. I’m in my late 20s and in good physical shape, so I want to maintain good sexual health and please my wife more in bed. Pumping seems like the safest and healthiest route, so I’m hoping to incorporate this into my normal health regiment, and add about 1/2” of girth. I’m doing stealth PE for 2 reasons: 1) My wife, though she’s opened up more sexually in recent years, might be weirded out and concerned by this. She knows I’ve had penis insecurity in the past despite being fairly big, and she might interpret this as a relapse (even if I tell her to the contrary). 2) The idea of surprising her with a thicker cock over time turns me on a bit and gives me motivation.

My pump just got here and I couldn’t wait for everyone to go to sleep (because I’m a damn kid at heart) so I snuck off to the office for some “work.” And got my very first session in. It was successful! I don’t have a gauge (I got a Leluv pump for cheap), so I was suuuuuper careful and slow. I was so nervous about not having a gauge it took me a while to get an erection. But once I did and I got in there, it was awesome. I took it slow and only added a little pressure at a time. Felt good (not orgasmic, but pleasant), and while I didn’t see a ton of expansion, I did see some great blood flow. Veins were popping. Held it there for 10 minutes, released the pressure, and worked up an erection and held that for a few minutes afterwards (per the advice on this thread). Looking forward to tomorrow.

I’m a former aspiring strength coach who believes in minimum effective dosage and I’m not in a hurry for gains. If anything, I want the improved EQ more than size gains. Thanks to everyone on this long, but helpful thread. I read nearly every page before I pumped today and I’ll keep you guys posted. Sorry for the saga-length post (a doozy for my first one), but I’m excited and had to tell someone haha.
