How to Use a Vac-U-Lock Strap-On Dildo and Harness

So, you’ve decided to take to plunge and give strap-on sex a red hot crack. Before you dive in, it’s worth making sure you’ve got the right equipment on hand or risk heartbreak with a side of blue balls.

First things first, you’ll need to make sure that you have a harness and a dildo and that the two are compatible with one another. Just like Goldilocks, you might want to take a few different sized and shaped dildos for a ride before settling on the shaft that’s just right. But what if your perfect faux peen doesn’t fit the harness?!

Thankfully, Doc Johnson has your back with their ingenious strap-on system. The Vac-U-Lock is the world’s very first fully interchangeable pleasure system that allows you to enjoy strap-on sex without having to worry about O-rings, flared bases, and appendage girths.

All that’s left to do is check whether or not the toy is Vac-U-Lock friendly and then you’re ready to bang! All Vac-U-Lock products are made from durable materials, so once you’ve invested once it’ll provide you with (almost!) a lifetime of pleasure.

How does it work?

Rather than fiddling around with interchangeable O-rings, Vac-U-Lock strap-ons feature a universal plug system that securely holds the attachment in place for pleasurable penetration. The lock system means that Vac-U-Lock harnesses are compatible with all Vac-U-Lock attachments, no matter the size or girth!

Each Vac-U-Lock attachment has been specially designed with a purpose-built hole at the base that perfectly fits the patented plug. To attach your dildo of choice to your harness, simply push your toy onto the plug and you’ll be ready to ride! No more fiddling around with different-sized O-rings to figure out which is compatible with your new dildo. Shopping for new attachments online has never been easier. You’ll be free to experiment with different shapes and sizes without having to worry if they’ll fit your harness.

As the name suggests, the plug simply ‘plugs’ into the base of your Vac-U-Lock attachment to create a vacuum-tight seal that even the most rigorous of pounding can’t break! The plug attaches to the harness with four snap locks, promising you security while you have a naughty while being easy enough to remove for cleaning.

To apply, simply squeeze out a good dusting of the powder into the hole at the base of the dildo you’re wanting to attach before pushing it onto the plug. This will help you to fix your dildo to the plug and harness while maintaining good suction. The powder is also ideal for maintaining the realistic feel of the Doc Johnson UR3 sex toys. Again, dust a little powder over your toy after cleaning to keep it feeling just like the real deal.
