How To Use Vac-U-Lock Toys And Why They’re So Valuable, June 2021

Have you ever thought that your dildo felt so much better than a dick? Have you ever been in the middle of sex, thought about your dildo, and just weren’t into the sex any more?

If you are in a lesbian relationship, have you ever wanted to give your partner the deep dicking they deserve, but you don’t… you know… own a dick? If you ever have, you’re not alone, I promise.

Luckily for us, there are certain modifications that we can make to our current penetrative predicaments that can totally turn our worlds upside down.

With Doc Johnson’s Vac-U-Lock, we now have a way to strap on our favorite dildos and take matters into our own hips. As easy as putting on pants, we can now put on our Vac-U-Lock, attach our favorite dildo and give our partners one hell of a pounding ourselves.

The old (and uber lame) cliche that men love to say is: “women--can’t live with ‘em, can’t live without ‘em.” Well, with the wonderful Vac-U-Lock in existence, it looks like us women will do just fine without any men, or their fun bits. 

Today, I will be looking at the Vac-U-Lock by Doc Johnson, as well as discussing how to use it in the context of a few of the toys that are compatible with it.

Because each toy is different, there can be slight variations on how to attach it to your Vac-U-Lock; however, they mostly follow the same formula. Doc Johnson’s innovation of Vac-U-Lock sex toys has given us women a chance to please ourselves and others the way that we have always wanted to be pleased.

What is the Vac-U-Lock?

Simply put, the Vac-U-Lock is a creation by Doc Johnson that serves as an attachment system for dildos.

You may have noticed that a lot of your dildos have holes on the bottom, right at its base. The idea for these dildos is to be attached onto the Vac-U-Lock, which creates a vacuum that allows the dildo to remain stable during use, no matter how hard you’re going. 

Since its creation, many other competitor companies have attempted to jump on the bandwagon and create similar products of their own, but Doc Johnson remains as the original. In fact, Doc Johnson’s model has become the standard attachment for most sex machines that are available today, so that’s always a good sign in terms of reliability and trust in the brand.

With adjustable straps, adjustable harnesses and an open jock strap-style back to leave the wearer’s bottom exposed for additional play, the Vac-U-Lock has all the makings of a high quality strap on. 

When it comes to size, the Vac-U-Lock can fit securely around any waist that is between 25 and 69 inches. It measures at approximately 40 x 60 x 40 inches and weighs around 9.9 ounces.

How to Use the Vac-U-Lock

How To Use The Vac-U-Lock, June 2021

The Vac-U-Lock is a simple two part system that consists of an adaptor with a plug or prong that fits into the hole in the base of a sex toy, and the sex toy itself, which is usually a dildo. With the strap on, you can easily and confidently attach your desired dildo or sex toy with complete assurance that it will hold securely.

In essence, the Vac-U-Lock allows you to turn your hand held sex toy into a hands free sex experience for both you and your partner. 

With this in mind as the general gist of how it works, this is not a complicated product at all. When you insert the plug or prong into the dildo hole at its base, it expels air and creates a vacuum and a vice-like grip. 

No matter how hard you go or how precarious your experimental sex position is, the continuous vacuum like pressure will keep the dildo in place. As a rule of thumb, always be sure to use a lot of water based lube on the Vac-U-Lock itself to make inserting and removing your dildos a whole lot easier.

Additionally, when removing your dildo from the strap on, be sure to tilt the accessories side to side as opposed to forcefully pulling it out straight, as that is a proven way to break the vacuum (and to prevent damaging both your dildo and the Vac-U-Lock.)

There are a number of Vac-U-Lock products, so let’s take a look at the wide variety of Doc Johnson’s product line.

Vac-U-Lock Suction Cups

With these attachments, you are able to mount your dildos to any smooth surface, from chairs and floors to desks and walls.

Doc Johnson Vac-U-Lock Suction Cup

Made from solid PVC, this Vac-U-Lock sex toy is a great sturdy base that provides a great deal of suction.

Because of the wideness of the base, it provides a high amount of confident durability and strength, making it able to stay still no matter how fiercely or excitedly you or your partner are gyrating.

This also makes for a great masturbation toy for self pleasure because of its strong suction onto flat surfaces. Being waterproof as well, you can easily bring this with you for shower play.

It is worth mentioning that because of the PVC material, the base itself may not be the most body safe.

However, with some care, responsible play and avoiding carelessness, you can certainly still have a great time with the toy--after all, this Vac-U-Lock is only a base that you would place your dildo onto.

During masturbation, some spots can still be hard to reach, especially if you aren’t yet a master of your hip movements.

Even if you are, there are only so many positions you can do while riding your planted dildo--for situations like these, there are products like this rotating suction cup.

This Vac-U-Lock base sits on a rotating ball joining that swivels in any direction, making it a great option for angle adjustability without ever having to readjust the suction cup.

All you need to do is place it on your desired area, attach your dildo, and let yourself go wild.


Mr. Hankey’s Heavy Duty Suction Cup

There’s a special place for size queens and kings ,and now there are special toys for our daring friends as well.

If your purchases were catered more toward size and excessive length, then this Vac-U-Lock is highly ideal because its purpose is to handle all the weight without sliding off the wall, moving on the floor or losing its grip anywhere.

There is a slight difference in design, as the prong for this one is rounded to make dildo removal easier and less likely to damage the inside of your toy. 

Unfortunately, the tradeoff here is that this Vac-U-Lock is heavier than others to accommodate the heavy weight, therefore it cannot be used as a harness or strap on. 


Kink Silicone Vac-U-Lock Power Wand Attachment

Teaming up with the BDSM giant, Kink, Doc Johnson created the Vac-U-Lock power wand attachment to add some vibrating fun into any orgasm sessions.

The way it works is that after you attach your favourite dildo onto the base, the entire Vac-U-Lock vibrates, allowing you to ride your dildo to your pussy’s content while enjoying the vibrations of the base.

As an added bonus, the attachment is made of silicone too, so the material is completely body safe. If you are hurriedly in a rush to get your cumming on, you can come home to this baby without any fear of unsafe chemicals coming into close contact with your little kitty.

Strap On Harnesses

With these strap ons, Vac-U-Lock harnesses are popular and widely trusted as very durable and stable enhancements to strap on sex. With these bad boys, you won’t ever miss a real life cock ever again.

Ideal for bigger toys, all you have to do is attach your favourite dildo onto the harness, adjust your straps to your body and bring your partner to pound town.

With the secureness of Vac-U-Lock, there is much less wiggle room, allowing you to really thrust to your body’s fullest potential.

Being compatible with O-Ring capabilities also, you have the versatility and choice to change up your sex session.

However, for longer, marathon esque sessions or during rough play, the strap on can get a little uncomfortable at times due to the straps and weight distribution, especially if you’re rocking a really heavy dildo.

Sex Machines

As mentioned earlier, Doc Johnsons’ Vac-U-Lock is the standard for many sex machines that are used today. There are a few companies that have tried to copy the product, but to no avail--there’s nothing like the original!

If you own a sex machine, you are aware of how fast and intense they can be. Despite this, the Vac-U-Lock secureness always remains firm, and the dildo stays on with the highest confidence. My jaw always hits the floor whenever I think about how steadily the dildo remains on, especially as the machine increases in speed and intensity.

Vac-U-Lock Tips

I touched on this earlier, but these tips require their own section because Vac-U-Locks require a little extra attention than the usual lube-and-insert formula of other sex toys.

Always lubricate with water-based lube. For best results in terms of your orgasm and keeping the Vac-U-Lock in good condition, use water-based lube to get yourself, your partner and your sex toys ready. 

Not all Vac-U-Lock sex toys are not body safe. Specifically, the ones made with PVC (instead of silicone) require some extra care and attention especially because they are going near your vagina. For these, it’s best to not take the whole length of the dildo to avoid touching the base completely.

Condoms work too. To save time on cleaning and to increase the lifespan of the Vac-U-Lock product, you can always use a good old condom on your dildo. Be sure to use a plain, non lubricated dildo and apply the water-based lube yourself.

Vac-U-Lock Storage can be pretty easy. Similar to most sex toys in general, allow your Vac-U-Lock to completely air dry to discourage mold and mildew buildup. Once it’s dry, store it in a cool and dry place instead anywhere too hot or where it’s prone to getting wet to avoid long-term damage to the product, and potentially to yourself as well as you will be using the product too. 

Final Thoughts

Vac-U-Locks are amazing products to have if you want to spice up your masturbation sessions or if you want to bring a new dimension into your sex life in general. By creating a vacuum like suction, you can securely attach your favourite dildo onto a Vac-U-Lock product and go ham until your body is out of orgasms.

Whether you are using Vac-U-Lock suction cups, Vac-U-Lock strap on harnesses or full on sex machines, there is a wide variety of compatible toys that you can use for your favourite dildos. 

No matter if you are a subtle cummer or a full-body, exorcism-esque finisher, you can be sure that the Vac-U-Lock will keep your dildo in place while your body moves uncontrollably. The Vac-U-Lock will have you never missing a dick ever again.
