The first time I used it, it blew my mind as well as my load. At first, it was very tight and hard to penetrate, but once in, it was an incredible felling that make you feel unexpected sensations. Its tight grip it created a good suction and amazing orgasms. Because it is so tight, it increase the intensity and sensation of the orgasms. After the orgasm, my penis felt numb, as when one feels after a long sex session.

I was having orgasms quicker that normal. Because of this, I was using this toy to train the delay time of my orgasm. But I think that it can also help deal with premature ejaculation with careful training. since it feels tighter than a regular vagina, if you get used to the toy, a real vagina would still be enjoyable, but not as intense in causing you to orgasm soon. Since it was my first toy, after using it, I also noticed that I felt a greater intensity of my orgasms with my partner, as if the product had unwired something in my body.
You might need a lot of lubrication, but not too much, since the tight grip of the product can spit your penis out. The outside ridges gave it a good grip.

The only problem was that it was too short so the end of my penis came out. To enjoy the suction more, the penis head has to be inside the tunnel. I came out the other side ofter. The inside of the tunnel can use more sensations, maybe by adding additional rings, or more defined. I didn't store it with corn starch, so it stayed sticky. Cleaning it was simply using soap and warm water.
Also, the piece can be used as a dildo, since it has a similar shape to a thick penis, so it can be a great teaser with a partner.

I had to throw it away because it was taking my time away, since it felt really good.
