A non-adjustable of the exact right size is really good at some things, but not at really long wear, .. plus our size changes if we're doing the PE right - making the correctly-sized selection more and more too small across time.
Good point on bolo-sliding. The style and
quality of a bolo is important.
The sliding, or locking, mechanism styles can be improved from iffy to great with a reasonably simple hack:
Get a silicone
sleeve, an old one is usually fine, a new ($) one if necessary, .. and cut off about a 1.5 inch length of it to make a shorter tube section.
This shorter length of the
sleeve/tube you can roll up like a condom and then easily roll it over and over itself down your shaft until it gets to the base, then unfurl it from a 'donut' back into a tube.
Use this as a cushioning material for
Two of the variable-sizing
cock rings, spaced slightly apart from each other .. atop the
sleeve section, but still all of it down at the base.
- Just like it sounds, now at the base of your shaft you'll have a 1.5 inch
sleeve cushion, with two
cock rings on it. -
Then push the whole 'assembly' further down until it bottoms out at the verrry bottom of your base, while holding it there - do a few kegels to get blood inflow jumpstarted above it, and you're good to go.
This works ridiculously better than one of the
cockrings by itself, and can usually be worn for far longer as well. Like, once you build experience and familiarity with it as a system, all night while you're asleep without fear of bad stuff. And obviously all day while running errands etc too. Just remember that less can be more. You won't need as much constriction force per
cock ring, so don't use as much. 50% as much occlusion force (per
cock ring) is going to be functionally similar to twice as much force from a single
cock ring by itself. Experiment while you're awake to find your right range before ever going on automatic.
(About the specific length of the tube, if you get it down to the base and it's not in -quite- the right spot when unfurled, a 1.5 inch section can be moved around to be in the right spot without much trouble. If you go to a 2 inch section, it becomes
Radically more difficult to move around, .. and a 1 inch section can be too short for having dual rings on it. 1.5 inch is kinda the sweet spot.)
If you can find a selection of
sleeve diameters, get one that is smaller than you are .. so it (the 1.5 inch cushioning section) will also help occlude bloodflow along with the
cock rings, all very effectively, but (since it's over a larger area) all very casually with no harsh pinching or bruising or retained color changes compared to the rest of the shaft.
Splitting some of the work of the occlusion force between multiple rings should also help to keep them from becoming accidentally loose/unlocked as much as a single ring.
