length in the tube

Just curious. Is your penis longer in the tube than your BPEL or shorter? and at what vacuum levels.

@5 inHg, mine is shorter in the cylinder than my BPEL. I am trying to figure out why.

Surely your girth is larger, sparky91…

Mine gets 1” to over 2” larger, than in “real life”, in the tube. On the last set of a session, if I wear it on a downwards angle (to wear baggy warm up pants and hide it), that seems to create the longest stretch.

I usually end up going to about 7 or 8 HG. As has been warned many times in here, and I can attest to it, you have to build up to that, or you will get many doughnuts.

Mine is shorter in the tube than my BPEL but longer than my NBPEL.

In my 1 3/4 tube my BPEL is 3/4 - 1/2 ” longer. In my 2” tube the BPEL is the same. I always pump at 4-6 hg and that remains constant.

Best,

I am 1/2” longer in my 1.75” and 2” cylinder than my BPEL.
I pump between 4 and 5.5 HG.

Editing to add that I have just realised about 3/8” is due to my curve being straightened out in the cylinder.

I’ve gotten to 0.5” longer than when I enter erect no vacuum in my 9 x 2 thick wall Vacutech. I am not packing the tube. I aim for max length gain, I assume it is also max girth gain while in the tube.

At the beginning I was .5 shorter (6.5” vs 7”)in the tube. Lately, after 3 months into pumping, I’ve been having the same measurements, slightly over 7”-7 1/8”. I think this has to do with the fact that I’m packing almost all of the tube now, so there is more pull. I usually pump at 5” hg, but even when going up to 9 for a couple of seconds, as an experiment, never get beyond 7 1/4”.

My length is about 3/4” to 1” longer in the tube than my bpl . I don’t know what the vacuum pressure is since I don’t have a gauge. Its probably pretty high, but I work up to it.

I gain about .75” length in the tube.

Haven’t pumped for a while. I got some pain after clamping so I’m having a girth exercise break. Just doing some light hanging. Anyway I was 3/4” longer in the tube then my BPEL at 6 in Hg during the first set. At the end of the last set (I did 3 or 4 sets) I was often more the 1” longer than my BPEL. If I watched some porn to keep my erection while pumping I was actually a little over 1/2” longer coming out of the tube than going in. This length “gain” subsided in a few minutes but it sure looked and felt great :)

Are you guys accounting for the height of the flange at the bottom of the tube? A pretty accurate way of getting a BP measurement in a tube is to measure from the base of the cylinder to the tip of the penis, and then add the height of the flange.

The flange on my LA pump is about 1/4 to 3/8” high, so I would need to add that to get an accurate BPEL measurement.

Of course, this isn’t exactly the same as jamming the ruler into your pubic bone, so there may be small differences due to how the fat pad redistributes around the ruler versus around the flange of the tube. In my experience, the flange gets pretty close to the bone, but it still might be up to 1/8” less close than the ruler could get.

This morning I proved the relationship to the tube diameter and your overall fit. Just for grins, I tried my old 2” tube. This is a thick wall tube with 1.75” ID. My penis fills this tube all the way up upon initial insertion. I tried this just to see the difference in stretch. With the smaller tube diameter, my penis has a stretch to 9.25 pretty quick. With my 2.25” tube it usually takes me a little longer to get to this measurement (about 15 min more) but I get more girth from the bigger tube (duh).

When I take my BPEL it’s normally at about 9.5” and after a good pump session (with varying pressure) in the 2.25” tube, my BPEL is anywhere from 9.75 to almost 10” but I wasn’t able to hit this longer BPEL after using the smaller tube (which I thought was odd). In neither of my two cylinders, can I hit the BPEL unless we add the flare as Modosto Man suggests.

So my long winded reply is I too am longer BPEL unless I add the flare to the tube measurement.

I’m really measuring length when I first enter (fully erect) the tube, and then how much longer it gets with my prefered level of vacuum. So far it is a .5 increase over time.

BoogieMan I personally think that the best length and girth penile stretch is done in a tube where you dont mash up against the sides. Unless one is really afraid of gaining anymore girth.

SiamGuy - I have to agree that we really need a slightly loose fit tube. I thought it was interesting that the smaller tube didn’t pull it forward more, focusing on length, more then the larger 2.25” tube like I thought it would. Another interesting observation was that my overall post pump BPEL length was better when I used the 2.25” tube. However, when I enter fully erect, prior to a lenghty pump, I still measure shorter then my normal BPEL.
