can someone tell me how this works

[Robert66]

I bought a pump thought was at least I can try to pump up before injection so I stop hitting veins I received it and there are NO instructions I mean it seems plain unit in one way pump its this seal its tapered and short are you suppose to cut it to fit or try to pump thru it I tried and hard to get anything tight its such a short piece

[Robert66]

Well i cant get a picture to show up but its rubber fits on base of tube is about 4 inches tall and tapered from tube size to about one inch .No way i think if you pumped.and your penis managed to make it thru that tiny hole would you not pass out from pain do you cut it to match your penis size ??

If you can find the pump on the internet you should be able to link to a picture displayed on the site selling it.

If I understand what you're talking about, you're talking about the flexible seal many of the novelty pumps have on the opening of the vacuum tube. How well that seal works for you will depend on your anatomy. They don't work for me. But the idea is that the the material is very flexible and as you pump it sucks your dick through it maintaining a seal as you gain engorgement. Personally I discard those. That leaves you with the option of using a lot of lube or doing some shaving if you don't already do that. If you ever plan to use silicone rings you will be doing some shaving or serious trimming. Anyhow, my suggestion is to remove the seal you're speaking of, trim and shave as required and use the pump without the seal. I think that should be sufficient for the intended purpose as you described. It may not be sufficient to pump up to the extent required for intercourse.

I agree... I actually shave and use lube. The wetness helps with the seal and you simply won't get a seal with pubes.

I have not got the science down yet I pump and it grows sure but as soon as I release pressure back down she goes.. I used it to get started so I can inject without hitting veins.

That's the way a pump works. Maybe you can pump and release a few times and get a nice "fatty", but it sounds like you want to keep your erection after releasing the pressure. Only way I know to do that is to slide a restriction ring on it while under vacuum. I don't know enough about injections to say if that is a good idea or not.

Two things. I did not want to shave so I submerge the bottom seal under water in my garden tub. Works great the water slows down the leak more than enough, And if compared to a naked mole rat or a wookie well I'm much closer to the wookie. Also if you pump is a ball and not a hand pump then you can fill the unit with water and have a much nicer experience. Water vacuum takes longer to stretch you out but the warmth on your penis is so very nice. Hurts much less at max stretch.
