Selecting Your Cylinder Size

Ok two more questions
1st- when I pump around 5-6 HG , my length stays around 7.1 but when I go close to 7-9 HG, Ican get up to 7.4. So should I try to keep myself around 7-9hg?

Also, I get that doughnut effect. Does this mean I need alarger cylinder?

I think that if you’re asking those questions, you probably haven’t read enough yet.

Most warn against vacuum as high as 7 - 9 inHg these days.

The doughnut effect is likely caused by you using too much vacuum or for too long a time. Try reducing your vacuum, reducing your session length, and taking some breaks during your session to jelq or massage your penis before resuming.

I know you are NOT suppose to go that high, but like many of us, I’m sure we all did the “what if” thing. Maybe I do pump longer than I should. I usually pump for 30 mins at 5-6hg. Maybe 2 or 3 sets and a I also do2 10 min clamping as well. I’m going for length this is why I was asking this question.

Also I can pack out my cylinder within the first 20 mintues

I just want to confirm. I am 5.3/4” base girth and wishing to work girth.

Will a 2” cylinder do the trick?

Thanks.

Yes, a 2” cylinder is perfect and will take up to at least 6.25” girth.

Sorry.

The way I wrote my size doesn’t look correct.

I am 5.3” / 5.4” EG. I can’t get a definite reading but I know I am 1.75” wide.

Just want to make sure :)

The same 2” tube is correct for you.

Well, I certainly should have started reading this thread from the top (where your chart is located). 25 pages (so far) is a lot of reading.

It does seem to me though that a single cylinder size with an assorment of modified inverted flare adapter caps would be more economical. Not necessarily less profitable either, since several finer size incremental adjustment sizes could be offered. And these can be easily engineered to be effectively airtight for the pressures pumpers use. Pipe threaded with a teflon tape wrap on the thread for example.

I envision a modified inverted flare adapter as traversing from the cylinder diameter towards a cone opening, then flaring back out a little for comfort.

Maybe I should start my own line.

Hi guys I have a problem I purchased two cyclinders the 1st was a 1.75 which was too small so I went upto a 2.00 which I am packing at the base I am not able to pump further as it takes the pressure over 5 to some where around 10 which I understand is a no no, so what am I doing wrong?

I am just curious. Can I still gain any length with a 2” cylinder (aim is for girth) if I get to a stage where I begin to pack my cylinder or can I still gain a little bit of length without packing?

Thanks.

I guess I am not able to sort this out

I am not quite sure what you are trying to do. If you are trying to pack up further from the base, you shouldn’t go for more pressure, but start adding more time. Keep the pressure at 5 or less and add more time in the form of multiple 15 minute pump sets.

That would be a good idea. You know what they say, if you want it done right, do it yourself.

Is flared cylinder preferred for comfort? The mustang penis pump includes 2Nr cylinders but the don’t appear to be flared. Or they still ok to use?
