A few features that i think could be nice on sleeves (some of which were already suggested before):
The ability to attach a vibration bullet to the sleeve (which can work for a variety of sleeves).
A sleeve with estim nodes built into them.
A sleeve which has a valve or connection system added to the top. This connection then could for example be used for
A 1 way valve to force only air out and create a stronger vaccuum.
Connecting something to add lube
Or just connecting it to a pumping machine to have both a vaccuum, or excessive air (to vary between sensations even more). Some machines can do this quite nicely without being excessive.
A sleeve that has a very big chamber at the end (to still be a closed sleeve, but act more like an open ended one). Open ended sleeves have the clean up part as their primary issue (as in, its not just the sleeve you need to clean up) so this might resolve that.
Sleeves in cases with adjustable diameters to increase or decrease friction. Silicon is strechtable but the damn plastic cases not. Most sleeves are too tight for my taste in the supplied cases.
A toy shaped like a hand, with adjustable fingers. Like the manicure schooling hands just more softer with stronger joints.
I only use Fleshlight Quickshot sleeves. The only prob is, they are too short. If they were twice as long and the case diameter would be a little bit bigger or like I said, adjustable. That would be great. The adapter to put two Quickshots together is not a good solution for me.
The problem with the 2nd thing is that fingers are generaly fragile, even if reinforced with some iron wire (which unlike most plastics can at least retain the shape after you move the fingers). I dont think this is going to work well with something like the handy. The movements are simply too violent for that.
If tension has to be adjustable, you can most of the time use tie wraps for that (some of them have a release button - just search for reusable tie wraps). The end point that sticks out can usualy be put aside with some regular tape (or some other methods).
The cases themselve (note i mean alternative cases, not the stock quickshot ones) often have issues because they can easily slip out the grip, or are too bulky in general. An extra wide quickshot case would do a lot though. But then the issue is how the sleeve would ensure itself to remain sturdy in the case itself. Using a tie wrap here is an easy and effective diy solution.
But ofcourse, an out of the box solution would be better. But im afraid that since they are competing companies that this simply wont happen.
…i use a really thick sleeve, with nubs all over the inside. The sleeve is so thick it doesn’t deform when it moves, instead it creates a vacuum at the tip. It’s a nice compromise between a squidgy traditional enveloping sleeve, and a big old solid fleshlight. I’ve tried various squidgy sleeves, like the ones from Handy, they’re… alright… but they’re really only a warm-up, big heavy thick walled sleeves for the win in my opinion. Yea, i also have a suction machine as part of my setup, which is why i have this sleeve, but my point is that even without using suction, the thick walled sleeve is far more pleasurable than the squishy deformative one.
If one could cast a thick sleeve with a solid band around the outside of it, where the Handy band holds the sleeve, then that would remove some of the pressure from the base, allowing a more natural feel, like the fleshlight, but maintain the weight advantage and the suction of the thick walled nubby sleeve…
Simply a piece of plastic or metal in the lips that holds them closed. Like a zip lock bag shape (the zip bit) but being hard plastic or metal they will want to snap back to flat.
Maybe this is a thing for some of you.
The ability to hold sleeves in place can be improved remarkable easy.
So obvious that i’d slap my forehead hard when this came into my mind.
You just need to remove the regular sleeve strap off of the handy and then, with a moderate and smooth movement, throw it as fast as you can to the trash and never ever think about it.
Replace it with a strap of some mtb / snownoard googles. ( basically just the one half)
Just do a loop by using the plastic width adjuster clip.
Easy to adjust, anti slip stuff at the inside and enough flexible to fit from semi-boner to rocksolid without going off. It even holds the open handy sleeves in position, which, on the other hand somehow still remain to be crap, anyways.
@op
A longer sleeve sounds interesting. Maybe with a thicker edge/barrier at the strap areas.
With or without condom is quite a diffirence in sensation. But since its a layer between the sleeve and skin, its always going to be of a lesser experience (which can in some cases be desired). But it obviously isnt going to be the best.
For a quick run it however does work at keeping things clean
A simple thing that can be done is using a small plastic bag, but that does require you to place it in such way it cant get stuck in the device. But thats still not ideal as it will generaly still leak onto the straps. And the bag cant be reused either (well, a few times as you can clean it, but for hygiene i wouldnt use it too much).
As the quickshots can be kept in nicely by the strap, this workaround works well for those as it can keep the bag closed with it. But the strap can obviously not avoid getting dirty this way (which can be resolved by having a few more of them so you always have some clean one laying around).
Also, when you place the condom over the sleeve, it makes the sleeve a lot more tight, which depending on the sleeve can be prefered not to have though (you can resolve it partialy by taking an excessive sized condom). It basicly does the same as the plastic bag solution except being generaly a more tight fit.
Part of the problem is these silicon sleeves have little to no thermal mass. I suppose you could embed tiny stones in the center of sleeve walls to store and release hot, but that conflicts with wanting to keep down weight.
So since pre-heating the sleeves isn’t an option due to lack of thermal mass, that just leaves:
Attaching a tube to the sleeve to steadily release warmed lube.
Embedding a circuit within the sleeve that can draw power from The Handy’s power source that keeps the sleeve at a steady but safe temperature.
Only 10 cm ? , Think a regular male is at lest 15-17, Myself 22, so 10 is a lite short , otherwise diffrent
textures, and maybe some tight and some more loose…
The Tenga products have some good features but more downsides.
The good;
Love the textures. they are intense.
They are inexpensive.
They are not too hard to strap to a device. I have an OSR with an adapter.
The downsides;
Mostly toooo small. Only the US models are even close to being useful as they are larger…
Self lubing, but cannot be reloaded realistically.
Designed to be one use product.
Stink. Even new I think.
I would consider the texture and material as an example of what could be useful.
Depending on the survey, results can be relatively accurate. Especialy in the more developed countries. There they often use information from condom purchases to verify these results. Oversized condoms on that are not comfortable so those purchases are quite reliable.
While they focus on width only (as condoms are generaly longer than needed to ensure a fit on length), it gives a good indication as a lot of lengths will generaly average out at similar areas.
And to get a comparison value on that side, in surveys they can often just ask, what is the value of the length divided by the width. This value is safer to ask since it doesnt care about your length or width in a seperate value, as boosting numbers will make other aspects look worse anyway:
If someone says a longer length, the number goes up, but it also means a thin cock which can feel like an insult.
If someone goes for a thicker cock, the value is low, which then could mean a short cock.
And those 2 warnings are enough to get people to answer fairly. There is no cheating here.
(and this might explain why certain countries show a significantly higher average, as condoms can be expensive)
