The Tenga Egg wavy is the first masturbation sleeve I have ever used. I was impressed by how easy it was to pour lubricant into the egg. For men who are a bit larger in terms of girth, there is often a concern about penetrating a masturbation sleeve. The Tenga Egg is so flexible that it can easily stretch to fit over both of my hands without breaking.

Inserting yourself or fitting the lubricated Tenga Egg over your penis is very easy. Once you are inside it is easy to figure out a number of ways to use the Tenga Egg to stimulate the penis. One way that I have found that works well when using the Tenga Egg on others is to hold the entrance of the Egg to the base of the penis with one hand and then pull the rest of the Tenga Egg up to stroke the rest of the penis. Pulling the Egg up so that you have more room to stimulate the head of the penis is extremely pleasurable. Since the entire inside of the Tenga Egg is textured fully encasing the penis in, the Egg will transfer stimulation to the entire penis no matter where or how you are moving the rest of the Egg.

The Tenga Egg has been very helpful for men I have played with who have difficulty achieving orgasm. It takes some of them hours to have an orgasm most of the time, even with a variety of acts and toys. The Tenga Egg is capable of helping me bring them to orgasm in a matter of minutes.

The Tenga Egg is made from very soft silicone that can stretch a surprising amount. I'm about 5.5 inches in circumference and I can stretch the Egg over both of my hands and easily have room to still fit my penis inside of it if I wanted to. It does not have as much of a "lint magnet" effect that you see with a lot of silicone toys. The "wavy" texture can most easily be described as "Heavenly." While the texture of the "wavy" and some of the other eggs looks a bit sharp or pokey, the soft silicone creates sensations of random changes in pressure rather than scratching. Because the Egg has only one opening, there can be a bit of suction during use, but this seems to be mitigated by how stretchy the silicone is. Air easily slips into the Egg if you want it too. You can easily create an air tight seal with your hands if you want.

The Egg wavy and the other eggs that I have tried all lack an odor.

The Egg is also very durable. While marketed for one time use, I have used one more than five times before I started to think it might rip soon. I probably could have gotten another 2-3 uses out of it before it ripped.

The Tenga eggs are all rather discreet. Unopened they just look like eggs that you might get from a gumball machine. Once opened and used, it is easy to hide if you need to. Too many people would think an open Egg may just be a random white blob in someone's room or on someone's desk. It resembles as a stress ball a bit. There is nothing that resembles genitals on the Tenga Egg (other than the fact that there is a hole).

Because of the degree that the egg can stretch, even men with penises of far above average girth can easily use the egg. Is it possible for two (or more) guys to share one egg at a time.

I tend to travel in circles with guys who have difficult achieving orgasm. While the egg is not very impressive when you look at it, it preforms extremely well. One guy that I have dated, normally took hours of work to get him to cum, had an orgasm in about 5 minutes using the egg on him. The Egg might not have bells and whistles and impressive packaging, but it delivers every time for me and any other guy that I use an Egg on.

Preparation of the Tenga Egg is quick and easy. You simply take the egg out of the packaging and squeeze some water based lube into the opening, squeeze the egg a bit to move the lube around and you are good to go. After use, it is pretty easy to turn the egg inside out and rinse away anything that happened to be inside of it. I have been able to wash out eggs that have previously been used with soap and hot water and used them again without much of a problem. With continued use, I have noticed that the Egg will start to get a little bit stretched out and will start to look like it is ready to break during use (after about 5 or more uses, depending on how much you stretch it). I kept a certain egg to use on a single partner and I have noticed that while the smell of their semen is a bit noticeable, the Egg did not pick up any of that smell. Or, the smell of the soap I used to clean it.

After I wash the inside and outside of the egg, I like to turn it inside out, stuff the smooth inside with a dry paper towel and let the textured side fully air dry. I'm a bit of a tech geek, so even when the egg is textured side out it just looks like some random piece of tech equipment. Also since the Egg is all white it helps it to blend into the background.

I wouldn't risk trying anything other than water based lubes with the eggs. My preference is wet lite.

The Egg comes in some of the most adorable packing I have ever seen. The Japanese "Kawaii" factor kicked in with this. It is bright and clean, unoffensive, with just enough of a metallic hint to make it look high tech.

While it is extremely easy to crack the Egg open, it isn't easy to put the halves of the Egg's packaging together again. I usually keep the halves around to use to kind of protect the Egg after cleaning it.
