This sleeve is to be used on a man's penis. I also tried it on a toy (vibrator) that was more slender than my partner's penis.

I believe anyone can try to use this sleeve, either on their penis or on a toy.

If you are able to get the sleeve onto your penis, it would be great for sex.

Using the sleeve on a toy was great for solo play.

The material is TPR and is jellylike. There is a faint odor if you press your nose right up against the sleeve. It feels soft, yet the nubs are firm.

The sleeve is pretty stretchy and seamless. However, I would think that over time the seams may come apart.

I loved the nubs on this sleeve. The top curves slightly and is solid jelly, which felt great on my G-spot.

The bullet is very powerful!

The shape of this sleeve is pretty standard. I liked the nubs and curved, solid top.

This toy was HARD to get on my partner's penis. He said it was very uncomfortable. We could not get it down to the bottom of his penis, so sex did not work out that great. We did try using lube to get it on, but it was just too tight.

It was very easy to get on a slender vibrator.

It is not adjustable and is "one size, fits all." I think this sleeve would work for someone with a penis size that is smaller than 6" and on the slender side.

My partner did not like this sleeve on his penis. We had a really hard time even getting it on. It did not cover his whole penis and was very tight fitting. We tried having sex, but it really wasn't that enjoyable for either of us.

I decided to put the sleeve on my Ultimate Satisfier Slim Vibrator. It worked A LOT better. I let my partner use it on me so he didn't feel left out.

I was happy that, even though the sleeve did not work on his penis, I still could enjoy it.
