You may have heard terms like "strapless strap," "double-ended dildo," "share dildo," and "partner dildo." If all those terms are confusing to you and you don't understand the differences, I'm here to simplify things by telling you there aren't any! All these terms more or less refer to the same toy, but this toy can take many different shapes. Let's get into it!
Defining a partner dildo
A partner dildo describes any dildo that is designed to penetrate TWO people at once. These toys are typically used for vagina-to-vagina, anus-to-anus, or anus-to-vagina penetration. Depending on the design, some partner dildos may be better suited to a certain type of sex than others.
If you've heard the term "DP dildo" or "double-penetration dildo," this is not the same as a partner dildo. A DP dildo is designed to penetrate one person's vagina and anus simultaneously.

The two shapes of partner dildo
There are two main shapes of partner dildos. One looks like two dildos stuck together at the base and the other has a bulbous shape on one side and a dildo on the other.
1. This shape of partner dildo is also known as a strapless strap. In theory, this design makes a harness unnecessary during strap-on sex because the bulbous end hooks into one partner's vagina and holds the dildo in place while they penetrate the other partner. In practice, most people require a harness to stop the dildo from falling out. But even with a harness, this type of partner dildo is super fun! When designed correctly, it can stimulate the G-spot and clitoris of the wearer as they penetrate their partner.

2. The second type of partner dildo looks more like two dildos connected in the middle. These are a little less versatile in terms of positions. The best and most intuitive way to use it in my opinion, is in the scissoring position both grinding onto opposite ends of the dildo and using each others hips for support. But you can also experiment with being on all fours facing away from each other and backing onto the dildo--though this can feel a little impersonal!

If you're wondering which type of toy is preferred by sapphics overall, here are the stats: 66% of sapphics said #1 is their ideal partner dildo while 34% of sapphics said #2.
Sapphics and partner dildos
Partner dildos are an incredible tool sapphics can use to deepen their connection during sex. They can let you feel the physical pleasure of penetrating your partner, a sensation that is often inaccessible or logistically complicated for a lot of the sapphic community. While it can be hard to find one that's just right, give it a try! It'll be worth the work once you get the hang of it!
