The Tenga Egg is different from most sleeves. It's shorter and wider, with at least 2" of inside diameter at the widest point, making the Tenga Egg almost as wide as it is long. This has lead to some consternation among people trying to use it. Slid over an erect penis it looks more like a shower cap than a masturbation sleeve. It does work, and well - you just need to adjust your expectations.

The Tenga Egg works because of the extreme stretchiness of the soft silicone material that Tenga uses. Once the Egg is lubed up you can easily stretch it to cover a 7" penis without the sleeve breaking. Unfortunately, as the Egg is stretched out the stimulation provided by the texture (1/2" ridges in the case of my "Stepper" model) is minimized, but the sweet spot for stimulation extends easily up to 4" of length.

But wait - there's more. Unlike most other masturbation sleeves out there the Tenga Egg is not limited to penises! Yes, you read that right - it's possible for anyone to use the Egg on themselves or anyone else. Flip the Egg inside out, slide it over a couple of fingers, and presto - you have a clit, vulva, or anus rubbing sleeve. Flip it back and it can once again go over a penis. What other toys can do that (and in safety, due to the Egg's ability to be sanitized)?

The Tenga Egg is among the few silicone masturbation sleeves currently made. Unlike most silicone, the Tenga Egg is extremely soft and stretchy, almost like the "real-feel" silicone used on other toys. Undoubtedly the Egg puts the soft silicone to good use - the texture, though very pronounced, feels quite good during use, and my Egg has survived multiple masturbation sessions with little wear.

Since it is made of silicone, care is very easy. Cleanup can be done in the sink with soap and water, and you can use almost any lube you want, either oil or water based. Silicone lube is not recommended with the Tenga Eggs, as silicone lubes can bind to silicone toys and the softer silicone toys seem to be more subject to the phenomenon.

Also, since the Egg is silicone, it is possible to sanitize it in a 10% bleach solution or by boiling for use by multiple people.

The shape is unique - it really does look like a hard boiled egg white (although the color is closer to soft boiled). It's stretchy enough to fit most men, but it's best if you keep the "working length" to about 4 inches or less. The wide cavity makes the Egg feel very different from the other sleeves I've tried - there really isn't much tightness from the Egg, rather your hand provides as much of a tight feel as you want. interesting, but a little different at first. The looseness definitely opens up unique options for foreplay or other extended-time fun, as the Egg can be lubed up and slipped over the glans ready to be squeezed and rotated around from time to time.

There is one tight spot on the Egg, a ring at the base. The tight ring at the base serves two functions: firstly it helps to keep the lubricant inside and any water (if you are using it in a shower, for instance) outside so your lubricant doesn't rinse off as easily. Secondly, it helps to keep your ejaculate contained. It's tight enough to do a pretty good job at both of these functions but at the same time loose enough to enable easy, comfortable use.

Undoubtedly, the Tenga Egg is one of the more hideable and discreet masturbators around. It's looks really don't say "sex toy" at all. Not having tried to take the Egg on an airplane flight yet I can't speak with authority, but my guess is that it wouldn't elicit comment from security unless you have wires nearby.

The Tenga Egg is a masturbator that definitely has a preference for how you use it, hand-held, single-hand. Making use of the stretchy nature of the silicone, the Egg really can't be held between pillows or any other objects and still be successfully used. I found that it was better with a single hand as well - with two hands I tended to loose my grip on the Egg when it got slick with lube, resulting in the Egg sliding back to the tip of my penis. Used single-handedly it worked well, both with a loose grip as well as when I tightened down.

Made from silicone, the Tenga Egg is fairly easy to store, since you don't have to worry about it melting. Since the silicone is very soft you do need to worry about mechanical damage. The Tenga Egg is best stored in the pack it came in which is, appropriately, a plastic egg. Washed, dried, and safely snapped away the Tenga egg will last you through several sessions.

Appropriately enough, the Tenga Egg ships in a shrink-wrapped plastic egg. Unfortunately the Tenga Egg ships with very few instructions, which has led to more than one confused would-be user. Tenga has a non-pornographic set of pictures showing the official way to use the Egg at on the Tenga Website.
