What to look for in a lube brand
Thickness, longevity, feel, scent, etc.
With many sleeves made of plastic, you must use a water based lube. An oil based lube will slowly degrade the your sleeve over time.
Certain sleeves with more aggressive textures can do better with thicker lubes while sleeves with thin walls, soft materials, or mellow textures do well with thin lubes. Fleshlight is an example of something you’d pair with a thin lube, even the more aggressive textures like Destroya as the sleeve has thin walls and the material is a bit soft.
Lube Brands
Gun Oil H20
On the pricier side. But highly recommended, well liked, and works well with many sleeves. It is more on the looser side which can lead to draining out of a sleeve. Doesn’t get tacky as it dries, and doesn’t dry out as fast as many other lubes.
Recommended to buy this directly from Gun Oil’s website. They have an email list that frequently gives 20/30% discounts.
ID Glide
More affordable. Very thin which if that’s what you’re looking for. It’s longevity is good, not great. It is very light, doesn’t leave much residue, and is easy to clean.
X Lube
It’s a powder you have to mix yourself, but it is fairly cheap. It’s on the thicker/stringier side but you can probably control that based on how you prepare it.
K Lube
A similar power supposed to have added preservatives to prolong shelf life of the product.
Sliquid
Fleshlight’s branded Fleshlube Water
Isn’t like water as name says but more like warm syrup in how it acts and lasts an lengthy period while going a bit of distance.
Tomax Branded Insomnia
Extremely thin and oil like, two small squeezes of this and it’s ready to go, one more and you start to lose feeling or risk leakage from even a vacuum like sleeve/onahole. If you want to feel then this is for you and I’ve never had this dry out on me.
O2 Lotion
Lube so thick and jelly like you’ll struggle to get it out of the bottle quickly. (It has air bubbles trapped in it) Does easily spread out and wet what you put it on so good for tight/anal like sleeves I’d say. You can also try diluting it.
ToysHeart branded Onatsuyu Pussy Juicy lube
Made to mimic pussy juice as the name says so it has a slight scent however is more like an kind of stringy lube. (container is horrible though to get the lube out of it)
Magic Eyes Branded IL Primo Bacio lube
Similar to above (but scentless) however mimicking mouth spit and so is even more stringy and sticky while still being somehow thin feeling. Was made specifically for blowjob onahole the company released. Supposedly has an sweet taste to it but I never dared to give that a try.
Apprentice Succubus Magical Transformation Lotion
JP only product. A thick, low-viscous lube to balance off the intense stimulation from certain onaholes. Recommended if you aren’t lasting long enough against your stroker toy.
