Siren is made for a wide range of users - men, women, and couples - and is a good choice for beginning to advanced users. You can use this as a stick-on dildo for showers, headboards, walls, and doors; it is harness compatible, and can also be easily used with just your hands.

Designed for penetration, either anal or vaginal, this has a nicely shaped curve for G-spot or prostate stimulation. Sexless and non-realistic, this is a dildo made for anyone to use. I do not have a harness and cannot take anything anally, but I had plenty of fun with this in the shower and with my husband.

Couples, men, and women will all enjoy the variety of uses of the Siren's design. I was pleasantly surprised at how much fun I had alone and with my husband! This one will become a regular in our toy rotation, and will be fun to continue experimenting with.

Made of 100% silicone, the Siren rates a 10 on the material safety scale. Silicone is nontoxic, phthalates free, nonporous, and hypoallergenic. It is also heat resistant up to 600 degrees (not that you will be testing that, hopefully). There is no odor or taste to this dildo.

The shaft area is fairly flexible and has a high amount of drag. Water based lube is recommended to prevent irritation from the drag and friction. The drag on your skin is very pronounced and actually hurts if there is no lube used. It does add to the sensations, and makes this a more pleasurable dildo.

There is no texture; Siren is smooth and does not have any seams. This allows for greater speed during thrusting or riding.The flexibility level is medium, which is firm enough to allow the curved tip to stimulate the G-spot or prostate without too much slipping and bending internally.

The base is flat on the bottom and is 3 1/4" in diameter. The flatness of the bottom makes it comfortable when placed against your body and used for thrusting (I used this by holding it with my hand and thrusting it into my husband's masturbator for this part of the review).

It is also perfect for sticking to a flat, non-textured surface for riding or thrusting. I used this in the tub and shower; it did not slip or move, and it held up to some hard riding very well. Pulling it off is a bit of a trick. Do not pull and stretch the material, but get a coin under one edge and pry the base up from there. The suction is incredibly strong!

The top of the base gently rounds and goes into the larger area of the shaft. This area starts at 1 3/4" and gradually gets smaller as it curves, down to a 1 1/4" diameter below the target bulb. The target bulb sticks up 1/2" from the neck and has a flat, oval top which is about 1 1/2" long, 1" wide, and 1/2" at the tip. The shaft is insertable to 6 1/2".

The black material is slightly metallic, with small silver flakes throughout. It is a serious lint magnet and does have a sticky feel to it--I rubbed some corn starch into the material to reduce the tackiness. It is non-discreet and looks like a sex toy. Travel would be easy if it is stored inside a pouch or shaving kit bag.

I love the shape; it worked very well for G-spot targeting. The medium level of flex was good for targeting and positioning. It was easy to insert, once I got it started. Getting this dildo started was a bit of a task in the shower and bath - the warm water made it flex a bit more, and gave it the rigidity of a semi-hard penis. Once I figured out the position and started the tip, though, it was a fun riding experience. I did try sticking this to the shower stall, but had a devil of a time with trying to insert it for thrusting. I will work on this prior to my follow up--it could be the motel shower stall shape, not the dildo.

I am unable to use this in a harness since I do not have one, but I did try this as a thrustee on a masturbator (not recommended for those with only two hands). It was a bit of a trick to hold this in place and also hold the masturbator, but once I figured it out, it worked wonderfully. There was no chaffing on my skin from the base, but I did only try this for about 7 minutes. I got lucky and did not get caught by my husband on that test!!

Wash thoroughly in warm, soapy water, and rinse well. Let it air dry, then go back over it with a sanitizing toy cleaner. Again, let it air dry. You can also wash this in your dishwasher, boil it for 15 minutes, and soak it in a 10% bleach to water solution to sanitize. I recommend these methods if used anally, if you share your toys, or after a UTI or other infection.

Store this separately from your other toys. This silicone is lightly tacky-feeling and may leach the colors out of other soft materials. It can also have a chemical reaction to components in other materials, which can cause the silicone to break down and deteriorate. That makes the Siren unsafe for further use.

Place it inside a plastic zip lock bag, and then it is ready to store. I also place it back in the thin cardboard box to keep the shape from getting pinched or damaged. If you are traveling, you may also place the bagged dildo inside a pouch, kit bag, or other container for discreetness.

~Toss in the fridge for cool temperature play.
~Soak in a bowl of hot water for warm temperature play.
~Rub outside with a minimal amount of cornstarch to prevent tackiness.
~Store in a dark/cool area to preserve the material.
~Stick it to a door for a nice hook for lingerie--add a couple more toys, and your partner will know they are going to have an enjoyable evening!
~Stick it to your seat in the car for a fun road trip (girls--wear a longer, flowing skirt for ease of insertion and discreetness).
