How to Use a Vac-U-Lock Strap-On Dildo and Harness
So you've decided to try strap-on sex. Before you begin, you'll need the right equipment!
You'll need to ensure your harness and dildo are compatible with one another. But what if you fancy trying a larger or smaller attachment? You might find that your new toy doesn't fit your harness.
To solve this problem, Doc Johnson have created an ingenious strap-on system. Vac-U-Lock is the world's first fully interchangeable pleasure system which enables you to enjoy strap-on sex, without worrying about O-rings, flared bases and appendage girths.
All you need to do is check whether the toy is Vac-U-Lock friendly, and you're good to go!
All Vac-U-Lock products are made from durable materials and chances are once you've bought one, you won't need to buy another for a very, very long time.
