The strap-on. Two words that still raise eyebrows in some sex shops, but that thousands of queer couples know, use, and love. If you're reading this, you're probably trying to understand how it works, choose the right model, or simply put words to something you've been wanting for a while.
Good news: you're in the right place. At Ma Joie, we make modular lingerie harnesses designed specifically for women and queer people. Not second-rate gadgets — products designed by people who actually use them.
What Exactly Is a Strap-On?
A strap-on consists of two elements: a harness worn around the hips or thighs, and a dildo that attaches to it. Together, they allow the wearer to penetrate their partner with their hips, freeing both hands for everything else.
Contrary to popular assumption, strap-ons aren't exclusively for lesbian couples. They're used by all kinds of bodies and configurations: lesbian and bisexual women, non-binary queer couples, trans people, and partners exploring pegging.
Types of Harnesses
Classic belt harness: worn around the hips with straps under the buttocks. Stable, accessible, works for many body types.
Lingerie harness — our specialty at Ma Joie — looks like underwear with a central ring. More comfortable, more aesthetically pleasing, and better designed for feminine bodies. Our La Brésilienne comes in XXS to XXXL, with a magnetic system to attach or remove the dildo in one second.
Choosing the Right Material
Medical-grade silicone is the gold standard. Non-porous, easy to disinfect, soft to the touch, and compatible with water-based lubricants. This is what we use for our magnetic dildos.
The Size Question
For length: between 13 and 16 cm (5–6.5 inches) is ideal for beginners. For girth: a diameter between 3.5 and 4.5 cm works for most people.

Lube Is Non-Negotiable
No penetration should happen without lubricant. With a silicone dildo, use only water-based lube — silicone lube degrades silicone toys over time.
What Ma Joie's Magnetic System Changes
Our patented magnetic system lets you attach or remove the dildo in one second — even mid-act. Switch from dildo S to M without interrupting the moment.
