Just did my first pumping session !

So I got this pump from Ali :

Pênis elétrico bomba sexo brinquedos para homens de carregamento usb automático pênis extensor bomba de vácuo pênis ampliador ereção masturbador,prolongador penian sexy toy,bomba a vacuo peniano produtos eroticos|Bombas e ampliadores| - AliExpress

It goes all the way to -55kpa (16Hg). The thing is, it only has two modes:

1- Automatic (Press one button it starts, press the other it stops, but slowly releasing).

2-Manual mode, fixed with 4 options
-30kpa (8.8Hg)
-38kpa (11.2Hg)
-46kpa (13.5Hg)
-55kpa (16Hg)

Now, TP wisdom tells me to stay the hell away from mode 2, so I’m gonna be sticking to mode 1.
Thing is, I wanna do it properly and stick to 3-4Hg, so I fire it up, it quickly starts sucking and when it gets close to 15 I stop. Usually I get it between 15-17 to stop (4.4-5Hg).
It drops down 1kpa every second, so that means I go from 17 to 10 and have to fire it up again back to 15-17. I got a bit annoyed and ended up letting it drop a bit more to 8 (2.2Hg) so I had to press it less times.

I am going to shave again, check lube, check if its not a seal problem of some kind, but in case that’s just how the pump works, do you think this cycling will affect the workout?

So I managed to improve seal so it drops a point every 3s or so, so I only need to repump every 15 seconds. The question remains though.

Does anyone know if pumping at a constant dropping pressure will impair the workout/gains? I’ve searched the forum but there is a lot about cycling which isn’t quite like this.

As your dick gets larger in the tube the vac pressure will reduce. Once your penis size has stabilized you should have a stable vac pressure. If the vac pressure continues to decrease you have a leak. The reality is you may need to pump every minute or so, but if you are pumping every 15 sec it is a leak.

The most common source of leaks are:
1) poor seal at the pubic-tube connection. Trim pubic hair around the contact area and using a lot of lube can ameliorate this situation. I use whatever hand/body lotion I have, but coconut oil and other lotions are also good.

2) hose connections are next. Does your cylinder have quick connect fittings or just a hose into the molded nipple on the tube? Quick connect fittings have several weak points. Make sure there is a good connection. Hold the hose and press it in to see if the leak stops or continues. The female fitting on the cylinder is often just placed had tight. Make sure it is not loose.

There is a small o ring between the female fitting amn the cylinder. Make sure it is not cut or pinched. If it is protruding out of the fitting it needs to be replaced. Most, not all, male fittings have a small o ring at the end of the fitting. There will be a slight recessed area for it if one is needed. Replace if missing or damaged. Most small hardware stores have a selection to chose from.

Replacement fittings are about $10 each. Amazon, McMaster-Carr, or your local hardware store. More info here:

3) next to check is the vac pump. If it is a pistol style pump the pressure relief lever can stick open so wiggle it to make aure it is not partially open.

4) check the hose to make sure there are not cracks or loose connections

Cycling is a disciplined approach. The drops you describe are just annoying and non-productive.

As mentioned, after a while you may be able to hit a sweet spot where the cylinder maintains its pressure alone or with only minimal help from you. Keep at it; it gets better.

Congrats on starting pumping. Keep us updated.

Thank you for the replies!

As I stated on first post, it’s an electric pump, so there isn’t a hose, hand pump, just the head of the pump (the pump itself) which attaches to the top of the tube, and the bottom part, which has a rubber/silicon ring to put the penis in. So the leak is either way.

Tonight I’m gonna try and put some thin film around the top part where it connects to make sure the leak it isn’t there. My last attempt to address the issue will be to try and pump without the O-sleeve, but this thing is just too damn big (almost 6.5cm diameter) for my BEG (~14cm) and i’m betting there will be ball sucking…
