In This Guide
'Double sided' and 'double ended' are used interchangeably in most marketing — but they describe fundamentally different products. This guide explains both clearly.
First: clearing up the confusion
When most people search for 'double sided strap on' they mean one of two things:
- A strapless strap on: One end inserts into the wearer's vagina (held by PC muscles), the other penetrates a partner. Both partners are penetrated simultaneously. Shared pleasure.
- A double-ended dildo: A long dildo with insertable ends at both tips. Both partners insert an end simultaneously. No harness. Each partner controls their own insertion.
These are not the same product. They have different mechanics, different learning curves, and work better in different contexts.
Strapless strap ons (shared penetration)
A strapless strap on has an internal bulb end (for the wearer) and a shaft end (for the partner). The wearer's PC muscles hold the bulb in place. The shaft points outward and is used for penetration.
Both partners are penetrated simultaneously. Every thrust transfers sensation through the toy to both ends. When it works well, it's one of the most intimate toy experiences available.
The learning curve: PC muscle strength and practice. See our full strapless strap on guide for detail.
Double-ended dildos (independent)
A double-ended dildo is simply a long dildo with two insertable tips — one at each end. Both partners insert an end and move toward each other. Neither end is attached to a harness.
This is a simpler, more independent experience: both partners control their own insertion depth and movement. There's no internal-bulb retention challenge. The physical experience is penetration at each end, with the dildo body connecting both partners.
Who each type is for
Tips for both
For strapless strap ons
- Use a backup harness for stability — many strapless toys are O-ring compatible
- Start in a low-movement position (spooning) until you're confident the bulb stays
- Kegel exercises build the PC strength needed for retention
For double-ended dildos
- A firm silicone material works best — floppy materials make coordination difficult
- Position facing each other with legs interleaved
- One partner can use their hands to help guide the dildo's midpoint
- Use generous lube at both ends

FAQ
Which is better — strapless or double-ended?
Different tools for different experiences. Strapless creates more traditional penetration dynamics with shared internal stimulation. Double-ended allows mutual penetration with more individual control. Try the one that matches what you're looking for.
Can a strapless strap on be used anally?
Yes — the shaft end can be used for anal penetration. The bulb end stays in the wearer's vagina. The same practice and preparation apply.
Do I need a harness with a strapless strap on?
Not necessarily — but a harness provides significant stability and is especially useful during active sex. Many strapless toys have an O-ring base for this reason.
