The answer to this question depends on what the artificial pussy in question is made of. There are many makes and models of artificial vaginas in the market, and each of them is made of various materials. The key here is to do your research and know which material produces an almost lifelike experience for users.
One of materials you'll see nowadays is Ultra Realistic 3.0 (or UR3 for short). It's a kind of thermoplastic elastomer and, as its name implies, it closely mimics soft, velvety human skin and makes you feel like you're touching the real deal. The best thing about UR3 is that it's hypoallergenic, so you can use it even if you have highly sensitive skin. Another option is CyberSkin, which imitates the warmth of human skin and provides a surface that's soft to the touch but has a firm layer underneath (basically like the human body).
More "traditional" materials can also make your fake pussy feel more lifelike, although not as much as CyberSkin and UR3 can. Silicone, for example, is soft and can feel like the real thing and quickly warms up to your body temperature. Jelly is also another option, although it's not as good in replicating the texture of human skin.
It's important to note that products made of UR3 and CyberSkin are more expensive than those made of silicone, jelly, rubber, and other cheaper materials, which isn't really surprising since they offer a more realistic experience. So, if you have the budget, you'll want to buy an artificial pussy that's made of UR3 or CyberSkin. This way, you'll get to enjoy the texture of a genuine vagina and easily imagine that you're making love with the woman of your dreams.
The "Realness" of an Artificial Pussy Also Depends on Its Design
If you've spent some time exploring your girl's vagina, you know that it has both ridges and soft spots. These variations in texture tickle your penis when you enter her pussy, and they greatly contribute to your mind-blowing experience. So why you should buy a blowjob machine that has a completely smooth surface? If you want your artificial pussy to have a lifelike feel, it should have the bumps and ripples that are naturally present in real vaginas. Fortunately, most artificial vaginas sold nowadays have textured sleeves that imitate the real thing, so it's not difficult for you to choose a product that makes you feel like you're entering a real, live woman.
Of course, when we talk about design, we don't just mean the inner texture of the product. We also look at the length that it covers. Some artificial pussies, for instance, mimic the entire length of the vaginal canal and make you feel like you're fully penetrating a woman up to her cervix. Others, meanwhile, only have enough space for your penis's head, making you feel like you're teasing yourself into your girl's entrance or like your girl's mouth is tantalizingly closing in on your schlong. There's no "right" or "wrong" choice; it's up to you to decide which experience you'd like to have!
Can an Artificial Pussy Mimic Real-Life Sexual Action?
Now this is a harder question to answer. The material and design of an artificial pussy can make it "feel" lifelike, but can it "act" like the real thing?
The answer to this depends on the make and model. Obviously, if it's just a plain masturbation sleeve that's made to look like a vagina, it won't really replicate the experience of having sex since you're basically just masturbating. You're in control of the entire experience so, no matter how you imagine being with a woman, your aching arm and hand will remind you that you're basically going the DIY route.
But, if you invest in an electrical pocket pussy, you can take your experience up another level. Electrical blowjob machines do the job for you, so you only have to insert your penis, sit back, and let your male masturbator do its job. You can even put your hands behind your head, close your eyes, and imagine you're making sweet love to your dream girl!
To be fair, some people find the action of artificial vaginas too "mechanical" and "repetitive". Still, the fact that you get to use an artificial pussy with a realistic material and design and almost-lifelike performance can make you forgive this flaw and give you one heck of an experience!
