The Aneros Progasm is one of the larger models of the Aneros line made to stimulate the prostate. The toy is used by contracting and relaxing the anal sphincter muscles and is not made for thrusting or movement by hand. Therefore, it may take time for you to get used to the toy and learn how to use it most effectively, so don't expect too much.

The product does come with some instructions, but they are not extensive and only go over some basics. A quick google search or just browsing the Eden forums and reviews should give you everything you need to know about using the toy correctly.

For those of you who may be wondering or misinformed, this is not a glass toy. Like most of the other Aneros products, this is a plastic toy. The only difference between this and the others is that this one is clear instead of colored. It is nonporous and mostly smooth with the exception being the center of toy where you can feel a small seam running down it. The Progasm is hard and rigid, which serves the function to place continual pressure on the prostate.

The Progasm is one of the largest Aneros models, so it may be the choice for those who are looking for something bigger. It has a length of 5 1/2" and a circumference of 4". When I first saw the toy, I was fairly surprised at how large it was. The shape is also much more aggressive than the other models and appears to be made for a maximum stimulation. The curves are designed to follow and fit the curves of your rectum allowing the large tip to put pressure on the prostate.

The toy also has extensions at the bottom that come out from the center. They are made to stop the toy from moving all the way inside and getting stuck. The one in front also stimulates the perineum from the outside. The drawback to this design is that it does not sit snugly with your butt. You can not sit down or rock on it, as the extensions push up and make it extremely uncomfortable.

The toy serves its function and does what it is designed to do. Once in properly, it sits there and will provide constant stimulation of the prostate. When you get your muscles to relax and are able to manipulate contractions properly, you may get some pleasure out of it. However, do not expect mind-blowing results. Everyone feels unique sensations when their prostate is stimulated, and it may take time for you to register it as pleasure. You may never experience it as complete pleasure or have a hands-free orgasm.

The extensions are terribly designed and do a poor job at everything aside from getting in the way. If pushed too far up, they can be very painful. They also prevent you from sitting down with the toy in, and the toy sticks out pretty far when it is properly inserted. There are only a few strict positions you can use this toy in.

Cleaning is pretty straight forward. Just use some soap and water, and you're good to go. There isn't much that can damage the toy during normal use, considering the material, so it should last you a lifetime.
