What’s your fetish? Like it smooth, veined? There is undoubtedly a dildo for you. Sexual pleasure is a primitive need among humans. Sex is primarily designed for reproduction/procreation, but scratch the babies; you still want to have toe-curling, sheet grabbing, lip biting, and eye-rolling orgasms without the entanglements of flesh and blood. Unlike before, sex is no longer as convenient as it used to be. Couples now add a bit of kink play to spice up their sex life, and singles explore to know their bodies better.
Do you think a dildo is not for you? Read our review of the best Vac-U-Lock dildos to see if you’ve been wrong. Are you of the opinion that plastic or silicone will not precisely “work it” as the real deal? After exploring the options from our list of vac U dildos we’ve reviewed in this article, you might change your mind.

The Perfect Cock by Kink isn’t just labeled perfect; there is a reason it is called that. If you are not exactly a fan of big and thick, we suggest you walk away, or you can take a leap of faith and never go back.

Unlike what you might imagine, the Perfect Cock by Kink is warm to the touch, phthalate-free, and body-safe, and that is why we have made it our special choice.
The Perfect cock by Kink special is its top-tier features designed to tease every hole with its dual-density design that gives it a soft, flexible exterior and a firm core. It is closely similar to Vac-U-Lock Ultraskyn dildo as they share squeezable realistic balls, although the latter is available in three shades of skin color. It is available only in black color.

More features: realistic feel, O-ring harness compatible, body-safe, pliable exterior
This dildo is made from TPE, molded directly by Porn actor Jason Luv Cock, sculpted to reveal every detail. It has a soft exterior giving the most realistic lifelike feeling, yet a firm core for the maximum possible stability. It begins with a thick base that extends into a realistically textured shaft and a bulbous head.
If your plan is to stretch all the way, Jason Luv Cock is all the dildo you need because of its mind-blowing girth. It is almost impossible not to derive satisfaction with this cock once you know how to work it. We feel that a dildo of 10″ with a diameter of 2″ is not thick enough. We would suggest that for a dildo of this length, there should be variations in the diameter to suit preferences.
What stands out?
Its realism can almost get it confused for a real cock, and that's why we like it because it feels just like one
The insertable length fills every hole and reaches all ends
What cons did we manage to find?
Variable girth options
Things to Consider
Doc Johnson Vac-U-Lock systems are the first patented sex toy and pleasure system in the world. However, many other brands have designed and produced their Vac-U-Lock systems after their design. Now, you’ve decided to get a dildo or another and are probably wondering why a Vac-U-Lock dildo makes the difference or the qualities you should look out for when purchasing one? This guide is the north star that will lead you to the perfect Vac-u-Dildo designed just for you.
Why Do You Need Vac U Lock Dildo?
One of the reasons you need a Vac-U-Lock dildo is the ease of use. A Vac-U-Lock dildo turns your handheld toy/dildo into a hands-free toy. It does this in two ways:
By attaching your dildo to a harness or adapter on a strap-on.
Attach your dildo to a suction cup on a smooth surface such as the wall, floor, or chair.
Before the invention of Vac-U-Lock Dildos, dildos and plugs were fit together and non-detachable, making them quite heavy. However, a Vac-U-Lock Dildo is usable with and without a suction cup.
Important Features
Color, shape, size, durability, price, maintenance, storage, cleaning. It is an endless list to sift through when trying to get the perfect dildo. However, we’ve eased you of this burden and highlighted the basic features to consider when getting a dildo.
Material
Dildos are made from various materials ranging from stainless, glass, PVC, Ceramic to Silicone. The best dildos are made from silicone. Apart from being safe to use, they give realistic looking and feeling dildos.
Vac-U-Lock Dildos are mostly made from Ultraskyn, a type of TPE/PVC/latex or Silicone blend that is flexible, soft, and stretchy. It also goes by the name soft skin, Cyberskin, or UR3. Ultraskyn blend is regarded as the most lifelike material in the world as it perfectly mimics a skin-like feel. It reacts to your body temperature and warms up just as an actual penis would. You, however, can run it under warm water before use if you desire the warmth on first contact.
Toys made from Ultraskyn cannot be sterilized because they are highly porous materials. Because of this high porosity, heat, radiation, and some strong soaps will disintegrate the material rendering it unsafe for use.
High-quality ultraskyn does not contain phthalates and is the materials we recommend for you. Signature dildos like Jax Slayher and Jason Luv Ultraskyn dildos are made from the best ultraskyn material. The best way to maintain Vac-U-Lock ultraskyn dildos is to use a designated toy cleaner formulated to clean this material and a talc-free renewing powder. While it is not compulsory to go for an ultraskyn dildo, it is important to ensure that whatever material it is made from is safe for your body, easy to clean and store.
Design
Vac-U-Lock Dildos come in various designs. Dildos are not always shaped in the form of a penis, even if they give an abstract representation of one. They are shaped to fulfill different requirements, do not be surprised if you find one shaped like a sword.
To give a representational look and give a realistic feel, the cocks are carved to highlight the features of a cock. The veins are intricately carved.
The beauty of the Vac-u-lock system is that it is designed to create any strap-on toy you desire, you just have to pop on an attachment of your choice, and you are good to go.
Length
Size, ultimately, is of personal preference. However, ensure that whatever length you are going for is what you can certainly handle and won’t injure you in the long run.
If you are new to the practice, it is advisable to start small and raise the bar gradually, even if you can take large cocks. A dildo, no matter how realistic looking and feeling, is still not a real cock and could cause serious damage like hitting your cervix if not handled properly.
The average dildo is 21% longer than a normal penis which puts the length of an average dildo at around six inches.
There are two lengths of measurement for dildos. The first is the full length which runs from the base, scrotum, to the shaft and up to the head. The insertable or usable length, however, is the length that can reach up totally into the vagina or anus. It reaches from the scrotum/balls up to the head and is usually shorter than the full length. Vac-U-Lock Dildos are available in various lengths to suit the desires of their various users.
Diameter
Just like length, the girth of a cock marks a huge difference to the user. The girth or diameter of a dildo is a measure of its thickness. The diameter of a dildo is the widest part of the dildo, which is usually at the base. It is measured by taking a measure of its maximum circumference, which is a full lap around the dildo, and dividing the result by Pi (3.24). Sexual orifices could be capable of expanding, but despite this, you should thread with caution when exploring the diameter of a dildo.
Another way to pick a dildo with a comfortable diameter for you is the finger test.
You can slip a couple of fingers inside you till you find a pleasurable and comfortable circumference, then measure it with a measuring tape. If you are going for a thick, large dildo, like Brysen ULTRASKYN™ Cock, it’s safest if it’s made from a soft material. Vac U Lock dildos have varying diameters. This is understandable because individuals have varying preferences for thickness when it comes to dildos. Toys made from the same material with varying diameters may feel like they have different densities- this can be attributed to the difference in size.
Compatibility
When purchasing a dildo, you should examine its compatibility with adapters and plugs. It would be a waste of time purchasing a dildo that is not compatible with your other sex toys like an f-machine. Special considerations should be taken when deciding on a base of a dildo.
Allergy information
For an object that will be going into the inner crevices of your body, it is important to ensure it will not pose a health risk.
Dildos are made from a variety of materials such as PVC, stainless steel, glass, and silicone.
It is important to read the list of materials your dildo is made from on purchase to ensure it is not a material you are allergic to. No one should have to end up in the ER after an orgasm.
Putting a Vac-U-Lock dildo into a harness is important for penetrative fun. The harness, which is the foundation or base for the strap-on, is the point of attachment for the dildo, and it fits both men and women. One partner wears the harness, and it is adjustable by the straps. To mount a Vac-U-Lock dildo into a harness, attach/dildo with one hand on the harness adapter plug while holding the other hand.
The adapter plug and attachment are designed to have a tight fit that will prevent the attachment from rotating on the plug during sexual intercourse. The first step in putting a Vac-U-Lock dildo into a harness is to ensure the harness and dildo are compatible.
Cleaning and caring for your Vac-U-Lock dildo after use is important if you want to experience and enjoy a repeat of the pleasure he gave you. Cleaning a Vac U Lock dildo involves the same process as cleaning a true Cock with some modifications.
Wash your dildo immediately after use: this is a golden rule. Although this may be the last thing on your mind when you are basking in the euphoria of your orgasm, cleaning it immediately after use guarantees another pleasurable time with your beloved little one. Wash thoroughly with mild, preferably fragrance soap and water before and after each use.
Pat dry with a towel or Lint-free cloth, do not rub on it to prevent the material’s surface from getting rough. Do not use paper towels (they break up, and the lint could stick and enter into your hole on subsequent use).
There are also cleaning products such as a sex toy cleaner. These are formulated to eliminate dirt and bacteria from growing on them. Usually, dildos come with cleaning instructions in their pack, and it’s best to follow the manufacturer’s instructions on cleaning.
Getting your money’s worth from your sex toy goes beyond the pleasure and the longevity or life span of these toys. Sex toys made from Ultraskyn are durable, provided instructions on cleaning and storage are strictly followed. How you store your sex toys determines how long they will last you.
Keep toys away from direct sunlight. Store in a cool, dry area.
Do not use Vaseline or baby oil on the toys. Only use water or Silicone-based lubricants.
Do not warm up in a microwave or oven. Some of these toys are expandable in contact with any form of heat. Sex toys made from stainless steel should always be kept dry, while PVC and TPE toys should be kept away from heat. (heat could cause an expansion of the material).
Our Verdict
All Vac-U-Lock Dildos are excellent in their way; however, our list includes the ten Vac-U-Lock dildos we believe to be the best in this order. The Perfect Cock by KINK tops the list of the best Vac-U-Lock dildos. No doubt, The Perfect Cock by KINK checks all the boxes of a perfect cock like the name implies, and that is why we chose it as the best on our list.
Our premium pick is the Vac-U-Lock™ Dual Density Starter Set because of the multiple attachments and accessories. We believe the Vac-U-Lock smooth silicone black is the best you can get in terms of value from pleasurability to price to comfort. When discretion is of utmost importance, we are glad this was considered when Brysen ULTRASKYN™ Cock was designed, thanks to the discreet travel and storage bag that came with the package. This thoughtfulness is why it is the best dildo for travel. Finally, we believe the Vac-U-Lock dildos are a genius contribution to the world of sex toys.
