UPDATE February 6 2016 WARNING: Topco has two versions of this product and vendors are not telling buyers which version they are going to get. One version is firm and the other is soft. I have both versions and really really like both of them. The soft version is like a zoftig woman's behind, nice and pillowy. The firm version is like a really athletic woman's derriere, muscular and firm. It has a very tight vagina that is gorgeous once entered, but that I found impossible to enter, until I figured out a method. The Amazon censors won't let me tell the method here (they rejected this update when it contained my description of the method). I have described the method in a comment attached to this review. If you can't find the comment, the censors deleted it, in which case please e-mail me through clicking on my profile. REQUEST TO VENDORS: Please identify which version you are selling -- the soft or the firm. -- END OF UPDATE -- I'm a senior citizen and believe frequent sex helps slow the aging process.. I love my wife dearly but she has mostly lost interest. By mid 2011 I found that flying solo with nothing more than mineral oil and videos was losing its appeal. So I searched Amazon for "artificial vagina" and since then have tried maybe 40 sexually stimulating products, several of them very good. With this item and several other toys I review elsewhere on Amazon, I am having a pretty good sex life, with an orgasm nearly every day. This is a new version of the Cyberskin Perfect Ass (CPA) that was brought out in 2014, which I bought about 17 months ago. It is tremendously pleasurable to use. The old version, that I bought in 2011, was made of much firmer material, but many guys found it difficult to penetrate because the vaginal entrance was so tight: I solved this through stretching it by passing a lubricated hand through the vaginal canal. At first I did not like this 2014 version as much, but with the passing of time I've come to prefer it, even though the 2011 version was really really great and is still in use. Having used at least 15 different artificial vaginas I find this and the Tomax Lilith Uterus are the two best, in terms of sensation and in terms of reliably bringing me to climax. The Lilith Uterus, is a sleeve, about 2 inches in diameter and 8 inches long, not much to look at but very effective. This product is a nicely made full size replica of a beautifully shaped young woman's rear, in late teens or early 20s, which is very sensual to touch and very sexy to look at. It is absolutely critical to use a good water based lubricant (without silicone). I started out using inexpensive lubricants from Target and Walmart, but these leave sticky residue and in fact work out to be less good as lubricants and more expensive and less convenient to use than several pump lubricants on Amazon such as ID Glide Frequent cleaning is needed to keep the vagina feeling smooth because otherwise lubricant hardens as it dries, producing roughness. This item is easy to clean because the vaginal tunnel is open at both ends so you can pour warm water through it . Brown University Health Services has (or had) an interesting article on the cleaning of sex toys, which concludes that it is sufficient to wash the toy in warm water, so there is no need to get special toy cleaners. I find that I can clean her very well using a funnel and half liter bottle of spring water. What I do is put her on the edge of a wash basin, put the funnel in her, then pour water right through, and then finish the cleaning job by putting my hand all the way through to manually remove any lubricant residue. The material she is made of is extremely stretchy, and I've done this numerous times without causing any viisible damage. A good feature of the CPA, that helps in cleaning, is that it can be totally immersed in water, if the skin gets dirty. It is important to keep the skin feeling soft and nice to touch through powdering it with cornstarch (and not talc) because otherwise the skin gets unpleasantly sticky. I place the CPA on a large sheet of cardboard (flattened pizza box) and spoon gobs of cornstarch on, then use a microfiber cloth to evenly spread the starch. A very very very important feature of this product is that it does not expel my penis if it gets flaccid. This allows me to keep going and to recover and get hard again. There are a number of products out there that expel one's member if it gets limp, which I find very unfriendly. The 2011 version is still functional and in use, though has a little bit of separation between skiln and substrate. This 2014 version is 17 months old and is still in good shape. A NOTE ON POSITIONING I have a bit of a beer belly and find that I cannot use the CPA lying down in bed. I find that the only way I can use the item is to stand on my feet and position the CPA so that it is at the correct height and correct angle. A real person's vagina is highly flexible in orientation, but this artificial one is more fixed and as a result positioning is very important. An easy method for achieving really good positioning is to find a sturdy table a little bit on the low side and then to use folded bath towels to add height, until the height is perfect. Believe me, it makes a huge difference. The best method I have found for achieving a really great position is to place the item on a swing, if you have the freedom to do this. I made an inexpensive and easily concealed swing costing about $35. I drilled two holes into a stud in the ceiling, installed two very sturdy hooks (3" long with 0.25 inch shafts), got about 30 foot of sturdy chain from Home Depot, 3/16" diameter and 1.25" links, cut a piece of plywood 12"x20" (three quarter inch thick) , drilled holes close to the 4 corners, and arranged the chain in an inverted Y shape. Placing a few towels over the platform insulates me from touching bare wood. This method demands quite a bit of work, but became exquisitely pleasurable once I got the height and angle of the platform exactly right. Starting out with the platform parallel to the floor, and at the right height, I experimented with angle (by gripping the edges of the platform with my hands and tilting it manually - not by adjusting the chain) until it was right. Took quite a lot of fiddling around, but all came right in the end. :) A really great thing about the swing is that I can stand still while CPA moves, or we can move in opposite directions, and I can even let go of CPA to move from its own momentum, which feels so natural and so nice, like being with a real person. To conceal the swing I just unhook it from the ceiling hooks and put it in a box.. The hooks in the ceiling are unobtrusive and could be used to hang plants or a light. In my case I told my partner about the sex toys, but as a matter of good taste, keep them out of sight. I find it helpful to put a sheet of smooth plastic (like cut from a plastic table place mat) underneath the exit hole of the vagina so that if one pokes all the way through the vagina, there is no abrasion on the penis. Also this catches any liquids. I find it helpful to watch videos. Currently I have a tower computer set up on a desk, with the video monitor placed on top of the tower, standing on the very edge of the desk, so that it is at eye level and very close to me, for maximum viewing convenience. I wish the manufacturer would enclose a list of approved cleanup products and detailed maintenance instructions. As noted above, Brown University Health Services has an interesting article on the cleaning of sex toys, which I found by googling "Brown University sex toys". This toy has totally changed my approach to solo sex, in a good direction. Instead of spending most time deeply plunging in and out, spend most time fully in, soaking up the sensations, moving in & out maybe an inch or less or more. Instead of focusing on seeking orgasm, focus is on just soaking, enjoying the warmth, moving minim
