A strapless strap-on (also known as a ‘share dildo’ or ‘double-ended dildo’) is a fantastic invention. The major advantage is that you don’t need a harness, which allows for more skin-to-skin contact and a much more intimate experience.
However, because you have to hold the toy in place with your own muscles, purchasing one involves just a little more than buying a regular dildo.
Here are the key points to consider when buying a strapless strap-on:
- The strength of your pelvic floor muscles
This is the most important thing to know: you keep a strapless strap-on in place by inserting the bulb (the rounded, short end) into the vagina (or anus) and tightening your pelvic floor muscles.
Tip: If you are not yet very trained in tightening your pelvic floor muscles, choose a lighter and shorter model at the beginning. A very heavy or long strap-on is difficult to keep in place and can slip out during thrusting.
- Pay attention to the dimensions of BOTH sides
When purchasing, you must take the anatomy of two people into account.
The insertion end (for the wearer): This is often bulbous or curved. Pay attention to its thickness. If it is too thick, it can be uncomfortable to keep it in place for extended periods.
The penetration end (for the receiver): Look closely at the length and thickness of the shaft. Remember that a shaft that is too long creates a leverage effect, making it easier for it to pop out of the wearer. Less than 15 centimeters is often the safest choice for beginners.
- The right shape (Ergonomics)
A good strapless strap-on isn’t just straight, but has a slight curve or a distinct thickening at the wearing area.
Why? This curve is designed to hook behind the pubic bone while simultaneously pressing against the G-spot. This not only ensures it stays in place better but also provides the wearer with delightful stimulation during every thrust.
- Choose 100% safe materials
Because this toy involves intimate contact with two bodies, hygiene is crucial.
Must-have: Always choose 100% medical-grade silicone (like the well-known Share or Feeldoe models). This is non-porous, easy to clean, and feels soft to the touch.
Note: Always use a water-based lubricant with silicone toys. Silicone lubricant damages the material of the toy.
- Extra options: Vibrations and ‘Plan B’
Vibrations: Many modern strapless models have built-in motors (sometimes on both sides!). A model with a remote control is highly recommended here, so you can easily switch settings during sex without having to search for a button.
Harness-compatible (Plan B): No matter how strong your muscles are, when things get wild, a strapless strap-on can sometimes slip out. Preferably choose a model that you can also slide into special strap-on panties (or an O-ring harness) for those moments when you want extra support.
