What is a Strap-On – and who is it for?

What is a Strap-On?

A strap-on (also: strapon, strap-on dildo) is a combination of a dildo and a harness – a wearing apparatus that fastens the dildo to the body, allowing for hands-free penetrating movements. The harness is worn around the hips and buttocks, and the dildo is secured in an O-ring opening.

Strap-ons are not a niche product – they are a versatile toy for a wide range of users: lesbian couples, heterosexual couples (pegging), queer couples, solo use with a suction cup dildo. The question isn't who a strap-on is suitable for – but rather which type is suitable for which experience.

What is Pegging?

Pegging refers to the anal penetration of a man by a woman using a strap-on. It is one of the fastest-growing sex toy categories – and for many men, it offers a new dimension of experience through prostate stimulation. More on prostate stimulation can be found in our Butt Plug Guide.

Strap-On Types: Which one for which experience?

What types of strap-ons are there?

Classic Strap-On Set (Harness + Dildo): Harness with O-ring attachment, separate dildo. Advantage: dildo can be changed – different sizes, shapes, materials. Most flexible option for those who want to combine different experiences with one harness.

Strapon Dildo (without Harness): Harness-compatible dildo with suction cup base – can be combined with a separate harness or used solo with the suction cup. SilikonLust Strapon Dildos are all harness-compatible and have a suction cup base for hands-free use.

Penis Sleeve: Worn over the erect penis – lengthens, thickens, or changes shape. For heterosexual couples who want to change size or texture without using a full harness. Platinum silicone penis sleeves are body-safe and fully sterilizable.

Strapless Strap-On: No harness – the dildo is held by an internal bulb in the wearer's vagina. Allows for simultaneous stimulation of both partners. More challenging to use – requires strong pelvic floor muscles for stable hold.

Strap-On Butt Plug: Combination of a butt plug (for the wearer) and a dildo (for the partner). The wearer is simultaneously stimulated anally. For those seeking simultaneous stimulation of both partners with a harness system.

Strap-On Harness: What really matters?

What is the difference between different harness types?

Single-Strap Harness (Jockstrap-style): One strap between the legs, two around the hips. Compact, minimal material, easy to put on. Advantage: allows simultaneous access to the wearer's vulva. Ideal for lesbian couples and anyone who wants simultaneous stimulation.

Double-Strap Harness (Two-strap): Two straps around the thighs instead of one between the legs. More stable fit, more control over the dildo. Advantage: more stable for intense use. Disadvantage: no simultaneous access to the vulva.

Underwear Harness: Harness in underwear form – discreet, easy to put on, no tangled straps. Less stable than strap harnesses, but sufficient for gentler use. Ideal for beginners.

What should you look for when buying a harness?

• O-ring size: The O-ring must match the dildo's diameter. Most harnesses have interchangeable O-rings in various sizes (3.5 cm, 4.5 cm, 5 cm). Measure the dildo's diameter before purchasing.
• Material: Leather (durable, shape-retaining, not vegan), nylon/neoprene (vegan, washable, cheaper), latex (body-hugging, but allergy potential).
• Size adjustability: Harness must fit body size. Adjustable straps are a must – do not buy one-size-fits-all without size information.
• Stability: An unstable harness makes precise movements impossible. The quality of the harness is just as important as the quality of the dildo.

Material & Safety: Why Platinum Silicone is Crucial for Strap-On Dildos

Why is platinum silicone the best material for a strap-on dildo?

A strap-on dildo has direct mucous membrane contact – vaginal or anal. The hygiene requirements are identical to those of a regular dildo. Platinum silicone is the only choice that meets all requirements:

• Non-porous: No bacterial growth, fully sterilizable after each use
• Phthalate-free: No plasticizers, no endocrine-disrupting substances
• Shape-stable: Retains shape and texture permanently – no tearing, no degradation
• Harness-compatible: Firm base for secure fit in the O-ring, suction cup for solo use

TPE strap-on dildos are cheaper – but porous and not fully sterilizable. For partner use, this poses a serious hygiene risk. More on material comparison in our article Platinum Silicone vs. TPE: What's the Difference in Sex Toys?

Using a Strap-On Correctly: Tips for Beginners and Advanced Users

How to use a strap-on correctly?

Communication first: Strap-on sex requires more communication than other forms of sex – especially the first time. Discuss pace, depth, position, and comfort of both partners. Agree on a safeword.

Put on and adjust harness: Put on the harness and adjust straps before use – not in the moment. Secure the dildo in the O-ring, check fit. The dildo should sit securely and not twist during movement.

Lubricant: Generously – always. Water-based lubricant for platinum silicone dildos. Especially important for anal use: the anus does not produce natural moisture. More on this in our Lubricant Guide.

Positions for beginners: Missionary position (receiving person lies, wearing person on top) – maximum control over depth and pace. Doggy style – deeper penetration, less eye contact. Riding (receiving person on top) – receiving person controls pace and depth themselves.

Size for beginners: Smaller than you think. For starting: 15–17 cm length, 3.5–4 cm diameter. The harness changes the perception of size – what seems manageable without a harness can be more intense with a harness.

How to clean a platinum silicone strap-on dildo?

After each use: warm water and mild soap. Full sterilization: boil (10 minutes), dishwasher (60–70°C, without detergent) or isopropyl alcohol 70%. When used with different partners or after anal use: full sterilization is mandatory. Harness: wash according to manufacturer's instructions – most nylon harnesses are machine washable.

FAQ: Strap-On & Strapon – the Honest Answers

What is a Strap-On?

A strap-on is a combination of a dildo and a harness – a wearing apparatus that fastens the dildo to the body, allowing for hands-free penetration. Suitable for lesbian couples, pegging (anal penetration of a man by a woman), queer couples, and solo use with a suction cup dildo.

What is the difference between Strap-On and Strapon?

No difference – both terms describe the same product. "Strap-On" is the correct English spelling with a hyphen, "Strapon" is the simplified version without a hyphen. Both terms are used synonymously in commerce.

Who is a Strap-On suitable for?

For everyone: lesbian couples (classic strap-on use), heterosexual couples (pegging – anal penetration of the man), queer couples, solo use with a suction cup dildo. A strap-on is not a toy for a specific orientation – it is a toy for anyone who wants to enable hands-free penetrating movements.

What size is suitable for beginners with a Strap-On?

For starting: 15–17 cm length, 3.5–4 cm diameter. The harness changes the perception of size – smaller than you think is almost always the right choice for the beginning. Communication with your partner about comfort and pace is more important than size.

What is Pegging?

Pegging refers to the anal penetration of a man by a woman using a strap-on. For many men, it offers a new dimension of experience through prostate stimulation. Ample lubricant, communication, and a beginner-friendly dildo are the most important prerequisites.

What lubricant for a platinum silicone strap-on dildo?

Only water-based lubricant. Silicone-based lubricant attacks platinum silicone. For anal use, apply generously – the anus does not produce natural moisture.

How to clean a platinum silicone strap-on dildo?

After each use: warm water and mild soap. Full sterilization: boil (10 minutes), dishwasher (60–70°C) or isopropyl alcohol 70%. When used with different partners or after anal use: full sterilization is mandatory.
