Smooth Wave

No matter your anatomy, the Neptune is a great anal plug. Those that have a prostate will enjoy it's curve for prostate stimulation. I lack one and still loved the full feeling that this hefty glass toy gives every time. I can't imagine life without my Neptune. The base is a loop that makes retrieval easy, or if you are into BDSM like me, can give you a new fun place to tie things to.
Comes with a storage bag
Great gradual shape
Loop on base
Too big for beginners

extremely useful review


The Neptune is a glass p-spot from SSA Glass. It is designed primarily to stimulate the prostate, but it is quite fun even if you lack a prostate. It could theoretically be used vaginally, but the design isn't as useful that way.

This is completely safe for anal because the loop acts as a base. The loop is large enough that it isn't a concern that this will be pulled into the body.

This is glass, so it is very firm. This means that you can bruise delicate parts if you are too vigorous.

Material / Texture

This is made of glass which is smooth and has a bit of weight to it. I like toys that have a bit of weight to them because I find that they are more noticeable during wear, but not everyone will feel the same as I do about it. This toy is rigid, so be careful with thrusting not to bruise anything.

The Neptune has no texture which is a must have for me with anal toys. I hate texture on my back door toys. The gradual shape makes it really comfortable during insertion, and the slight curve will stimulate the prostate for those that are equipped with one.

Glass has no odor or taste, nor does it hold on to any because it isn't porous.

Glass can be used with temperature play. this can be warmed in hot water or cooled in ice water 15 minutes before use to add new sensations.
    • Not porous at all
    • Rigid

Design / Shape / Size

This is specifically designed as a prostate stimulator because of the curve, but that can also make it useful for g-spotting if yours happens to be shallow. The looped handle instead of a flat base makes it much easier to use solo or to have a partner use it on you.

This is completely rigid and weighty, so beginners may find this a challenge, but more intermediate users will enjoy the 5" circumference. It's about 6" long but only about 4" is insertable. There is a nice long thin neck which makes it easy to retain if you are using it like a plug. The loop is about 2" wide, so most people won't find it comfortable for sitting on because it sticks out pretty far.

The tip is very gradual, so it slowly works you up to the larges part of the bulge. I prefer toys like this because it is easier for me. The tip is not pointy at all even though it is absolutely a point which maeans that during wear, this is still very comfortable.

I can't really call this design discreet. It looks like a sex toy to me, but it is small and easy to tuck away.


The shape may be intended for prostate stimulation, but I lack a prostate and still found this extremely pleasurable. When I am riding my partner with this inserted, I can most definitely feel this getting pressure from his body. I find it intense but enjoyable. He finds that he can feel it in my vaginal canal, and it is slightly uncomfortable for him.

Glass conducts vibrations well, but it is loud about it. You can take a small vibrator and put it through the loop if you need vibrations; just know that it will be loud.

    • Easy to use

Care and Maintenance

Glass is an amazing product when it comes to care and maintenance. It is compatible with any lube or mild cleanser including toy cleaners and you can sterilize it by boiling it, putting it on the top rack of a dishwasher, or by wiping it with a 10% bleach solution. You can also wash it with and mild soap or toy cleaner and warm water.

I would recommend storing this in a location where it won't fall on to the floor. It is hard to break glass toys but not entirely impossible. A fall onto a hard surface too often may just do it.
    • Easy to clean
    • Easy to store
Follow-up commentary
This is probably my second favorite plug. The curve fits my anatomy perfectly. I love the loop instead of a base because it makes insertion and retrieval so much easier. It is a bit on the larger end for me but so worth it.
