Of course as usual I always find me some type of gadget to try out on my husband. When I whip it out he always says the same thing, I do not know what you have that for, you are all I need. He then looks at me smirks and give me another look like I know you are not going to use that on me. Of course I always do, laugh out loud. So I tried this on him, by the way yes it does moan. I played with it for a minute and it was pretty nice. I could see the tongue in it or maybe what is supposed to portray a vagina wall, it was moving up and down. It was very different from other masturbator cups that I have bought and tested before. Oh did I mention that you plug up headphones to this device and it moans, ....yes, it moans. The tongue or what reflects one actually clamps down gently in a massaging way, the stroker also vibrates on 10 different vibrations to match the 5 different clamping actions. It is very unique from the other devices we have tried and very intriguing. I do have to say that he says that he says without luberication it is not the best feeling and not a natural feeling.So I recommend this for self use or for couples, I think it will be well worth the money.
