The Nexus Silo is, unashamedly and unabashedly, a prostate toy. It's shape, size, design and execution are all focused on the sole objective of prostate massage. I know this seems obvious, but it bears repeating. This is not a butt plug, nor is it useful as any sort of dildo for vaginal use; this is a prostate massager, nothing more and absolutely nothing less. And it's damned good at what it does. The Silo slips into place after some warm up, and makes its presence acutely felt. It is no shrinking violet, and it is not a beginners toy...but for prostate owners who already tasted the joys of a P-spot massage? The Silo will provide.

The Silo is made from medical grade silicone and is thus non-porous and easy to care for. This particular silicone has a bit of a velvety feel to it - a brushed 'finish', almost. It is also very very firm silicone - it has a shape, and it does not bend to accommodate. All this adds up to a toy that does not pick up hair and lint quite as readily as softer and slicker silicone toys.

To those familiar with the Nexus product line, the Silo might seem familiar. It is the same shape and size as the insertable portion of the Nexus Gyro, a novel toy with a reputation for being powerfully effective, yet a little awkward and specific. In many ways, the Silo could simply be considered to posses the best aspects of the Gyro while removing the awkward and specific use gyrating 'ball'. However, the Silo takes it one step further, 'finishing' with a lovely little base whose shape and size is reminiscent of the universally adored Tantus Ryder base. This base, while providing sufficient flare (due in part to the rigidity), allows the Silo to nestle securely between butt cheeks. The reason this is just *so* awesome is that with a butt clench, the Silo is gently nudged back into perfect position. It's not exactly self correcting, but its truly amazing to not have to use your hand to adjust.

Base aside, the shape of the Silo is crafted perfectly to fit ergonomically into the ass, working with natural contours (which is good, because it is very rigid) and angling to provide specific and concentrated prostate massage. It is girthy - 1 5/8" diameter at its widest point - and it does not really feature a significant 'neck', so it will hold the ass a bit more open than more classic prostate massagers (like the aneros line) would. This lack of neck of course is a consequence of specifics of the Silo's ergonomic design, but does allow the Silo to slip out slowly but surely when the ass is sufficiently relaxed. However, as noted already, the base's design allows it to be snugged back into place (in a pleasurable way, I am told) by clenching butt cheeks. Smart.

Like most prostate massagers, there's a learning curve with the Silo if you wish to use it for a hands free prostate orgasm. If you want to rock the whole clench-release slow build up, the Silo will feel a little harder to move than a plastic massager (like the Nexus Excel), but its generally larger, so the movements it does make will be felt significantly. The Silo is better, it seems, as a prostate massager to be integrated into other sexual acts. The act of thrusting, for example, will clench the Silo nicely into place, nudging the prostate in the process. While this could be said of many prostate massagers, the Silo's base provides a very very small foot print that will not get in the way. As well, the Silo has no perineum massager - a feature common on 'butt-plug' style prostate massagers, which can be distracting and can get in the way during sex. My prostate owning product tester was beside himself with joy at the lack of perineum massager - he went as far as to say it would be way too much sensation to have a perineum massager with this toy (but I gather some men might see this as a large negative, so your mileage may vary).

The Silo is pure silicone, so it should not be used with silicone lubricant. As a toy designed to be used anally, it should not be used vaginally (which would serve little purpose anyways), unless properly sanitized or used with a condom. The same is of course true if it were to be shared with a non-fluid bonded friend. For every day cleanup, however, a good scrub with antibacterial soap and hot water will do.

Like most Nexus products, this comes in hard-ish plastic case - a clamshell in this instance. It could be used for storage, but I would suggest living dangerously and just tossing it into your toy storage unit or bedside drawer by itself, instead. The instructions are rather light, but then again, each individual will find his unique groove when playing this this toy, so they are sufficient if you keep that in mind.

Being that I am female bodied, I don't (sadly) have a prostate. As such, I can't really comment on how totallyawesomeamazing this toy is, but that's essentially what my testing buddy (who DOES have a prostate) told me. But I did wear this toy every way I possibly could in an attempt to make it work for me - to no avail. I found it decently enjoyable if I wore it pretending I did have a prostate for it to massage, mostly because I was very impressed at how easy it is to keep in place with butt clenches. I was also able to appreciate how effective it transmits a butt clench into a massage in the prostate region (and no, it did not hit my G-spot, the angle is wrong). It was far too curved to be comfortable placed in any other orientation in my butt, and as a 'cunt-plug' it only felt vaguely pleasant when in so that the curve was aimed towards the rear wall of my vagina.
