OK, I have to say that my wife ordered these. Now, I'm almost 100% certain that she was not trying to help me on my quest for the best his/hers cock ring set. I think she just wanted them for the colors and designs. Anyway, on to the review:

The Senso 6 Pak is made by California Exotics. There are six different colors and shapes. This product was designed with women in mind. Most of the rings I have tried so far try to touch on that in some fashion. For the most part, if I put on a ring and it is the right size and constricts blood flow out of the little guy, it works for me. Many leave my wife's pleasure lacking, except the little guy gains a bit more girth. These address that issue without using an additional vibrator first.

The nice thing about this product is the fact your partner can experiment. You can use more than one ring, different shaped rings and also change placement on the penis. They are a bit more versatile compared to the traditional rings. They can be placed at different locations on the penis, while you have one on at the base for that added girth and longer lasting erection. Be Careful! You do not want to lose one of these inside. If in doubt- Don't!

I would also rate these for beginners and advanced alike. The nice thing is that a change in placement or shape will take her to another different experience. The combinations are many, so it is hard to become too familiar with this product.

The rings are made from Senso-Plus. It is a man-made material that is in the line of jelly rubber. It is made from a Poly Vinyl Chloride with softening agents added. It has a feel similar to silicone. This is also a toy that can easily harbor bacteria, but I will get into that more in the Care section.

The material is semi-sticky, meaning that it will attract dust, lint and hair. It is not really sticky to the touch, but it somewhat wants to stick to itself.

There is a slight smell to the rings, but for the most part you would have to really go looking for it. It also isn't an unpleasant odor, so there is not much to worry about as far as that goes.

The material is also quite stretchy. The hole is 1/2 inch in diameter and can stretch 2+ inches in diameter. Now, I know the product page says 3 inches, but I would recommend a maximum of two inches for comfort. A normal size coffee cup is 3 inches in diameter.

The rings are tight enough to add girth, but most important, they are tight enough to stay in the location you choose on your penis. They aren't so tight to cause discomfort though. They don't seem to want to slide around too much, but I would suppose that will depend on the lube and amount of lube you use. My wife and I didn't use lube for this product.

OK, first I will discuss the size and fit. As I stated before, it has a 1/2 inch diameter hole that is stretchable to 2+ inches. The actual ring body is 3/16 inch by 3/4 inch long. There are approximately ten ribs on the inside of the ring, which helps to keep the ring from moving and also "stores" lube, if you use lube, for easy removal.

Each color has a unique shape:

Orange has 8 full size teeth and 8 smaller teeth. It looks like a gear.

Blue has 8 pointed spikes. It is similar to a spiked dog collar.

Green has 4 rounded spikes. They look similar to a rounded arrow head.

Yellow has six 3/8 inch ticklers, 3 to a set. It has 4 single nubs and 2 double nubs in between. It reminds me of 3 old pirate ship wheels for steering.

Pink has 8 rounded balls with one small nub on the inside and outside. Reminds me of an old fashioned chandelier.

Purple has 6 small nubs in a front and back ring. The center ring has 14 ticklers. It, again, reminds me of a boat's wooden steering wheel.

As I have touched on before, they are great for your partner to experiment with. Set it up any way you want, and just have fun experimenting!

Doing some research on this material (first time we have used it), Senso-Plus is a man-made material that fits in the category of jelly rubber. It cannot be boiled for complete sanitizing. It also harbors those nasty little bugs called bacteria. Recommended cleaning method is to use toy cleaner or warm water and soap. Again, use a condom if you share. Please note that you need to put the cockring on first and then the condom, other wise you are risking breakage. I recommend not to share.

The other minus is that it is easily stained and not so easy to remove it. It can also degrade at higher temperatures. It is only compatible with water based lubes, so my best advice is to take caution when you use these and be very careful on storage.

Speaking of storage, my wife and I use the packaging it came in. Each ring has its own cell, so they don't touch. It also prevents other things from touching them. The material attracts dust, lint and hair, as well as bacteria. I would be apt to recommend a Ziploc bag for each, but they may stick too much to that surface after awhile. I have not tried that, but if one breaks or becomes too bad to use, you will see that in my follow-up.

The package shows the back of a nude female being held by a nude man. It says SENSO 6 Pak. It is from California Exotic Novelties and states they are super-stretchy enhancers. It says it is hygienically superior material and to use a rubber compatible lube. Please use only water based!

The package is in no way discreet with the insert in it. If you remove the insert, it's a bit better. There are no directions for use, but it's pretty self explanatory. I highly recommend using it as a storage kit for the rings. It is hard plastic and hinged at the bottom. It should keep them safe for some time to come.

OK, as I said before, this set was my wife's pick. I think she fell in love with the colors. I'm not sure if she intended on using them, or just finding a way to display them. Yes, I did manage to put them to their appropriate use.

We are still working to find the combination that suits her. Yes, we are on more than two at a time now. The different positions and combinations of design are mind boggling. It may be some time before she picks the favorite. I hope I can last and the product lasts to see it through. We can always buy another product, but I'm one of a kind (had to toot my own horn).

We had some concerns about them coming off inside her, but in the multiple times we have used these so far not a one has gone astray. They could be used for both male and female masturbation. The only concern this reviewer would have is if you put it on a solid plastic vibrator and used lube, it may have a tendency to slide off. Be careful, and try before you actually try it for that use. Do not use for anal insertion!

Now for my wife’s thoughts and possible confession on why she purchased these:

My husband is nearly correct in his theory; I bought these for their colors, cuteness factor, and price. When they finally arrived I did not have any expectations of these doing anything at all to enhance our sexual experience. They look like some kind of kid’s toys or those new gel window decorations.

When we began using them one at a time, the only thing I did notice was a small difference in girth. This was nowhere near the same difference as my experiences with other cockrings. I believe the material is the flaw in not being able to feel any enhancements; these seem to squish when body force is applied.

My husband then decided to inform me that we were going try a couple at a time, and I nearly fainted at the thought. We bantered back and forth before he convinced me that they would be tight enough that we would not lose any. This is not something I wanted to have to go fishing for later. He was correct, as using multiple is the only way you can feel any sensations with these cockrings. I do not have any favorite combinations as of yet, but hope to by the time our follow-up review comes due. That is if they last that long, since they really look like they could break easily. I seem to enjoy the orange, pink, and blue cockrings, as they have more solid and thicker extensions as opposed to the little brush-like ones.

I would recommend only doing this if you feel comfortable doing so or you have a lot of trust with the person you are with. Otherwise, I would just skip these altogether if you were planning on using only one at a time.

I store these separately in the package they came in; I have learned that storing them together can cause the colors to bleed into each other. I also did not notice any real scent to any of the individual cockrings, as the product description described. There was a faint odor when first taken out of their package but that soon went away.

These can be used on a vibrator as well, so solo play is an option with these little cuties. I would recommend these to anyone looking to experiment with variations of multiple cockrings.

The price is nice enough that replacing them is not a problem when they wear out or break.
