tube size toss-up, but...
liquidlust 1,
I agree with Avocet8 that your current 5.5 girth puts your decision making right on the fence. To help you make your choice, I have a few comments to make.
Depending on your budget and how serious you think you might want to get into incorporating pumping into your PE routines, I suggest that you start with the 1.75 inch diameter and then eventually move up to the 2.00 inch. I’ve been pumping for awhile and even though my erect girth width reaches 6.75 inches unpumped, I still like beginning my pumping sessions in the 1.75 inch tube. This size gives my dick the opportunity to “pack” quicker and more fully and evenly up the entire shaft and gives me real good stretches for better length gains. You’ll be able to get several months worth of good and effective use out of this size alone.
I then move to the 2.00 inch size and continue the pumping session. With my dick already expanded from the 1.75 inch tube, it makes the “packing” in the 2.00 inch tube again faster and more effective. Again, I believe that this kind of transitional pumping gives me personally the most effective and lasting results. When time permits and when I really want to push the pumping envelope, I move up to a 2.5 inch diameter tube.
Points to note for beginner pumpers:
1. If the tube diameter is too big, it takes longer to achieve an effective pump
2. If the tube diameter is too big, it may be more difficult to get a good seal
3. If the tube diameter is too big, the ballsac may get sucked up into the tube.
For some this is desirable, but if your goal is to concentrate on your dick, then
consider this possibility.
Pumping size math info:
1.75 inch diameter = 5.50 inch circumference
2.00 inch diameter = 6.28 inch circumference
2.25 inch diameter = 7.07 inch circumference
2.50 inch diameter = 7.85 inch circumference
Don’t let the sizes above confuse your pumping decision. Remember that when you pump in the tube, your dick is pliable and adjusts/squeezes into the tube shape in which it is housed. So a good tightly”packed” pump in a 1.75 inch tube (5.5 inch circumference), when released will result in an expanded and relaxed pumped dick bigger than 5.5 inches circumference. Again, the priority here is effective pumping, rather than trying to overreach too quickly with a bigger tube.
This is a much longer response than I had originally planned, but I thought all of the details needed to be given for you and others to use. Let us know what you decide to do and how it all works out. Good luck!
