Using a Strap-On: The Beginner's Guide for Couples & Solo
A strap-on isn't a complicated system. There are three components that need to fit together – and a first time that, with the right preparation, is straightforward.
This guide explains everything you need to get started: which harness, which dildo, which positions – and how SilikonLust platinum silicone toys elevate the experience to another level.
What a strap-on is – and who it's for
A strap-on is a wearable system that secures a dildo to the body – hands-free. The dildo sits in a harness worn around the hips or thigh. The wearer can penetrate without having a penis – or in addition to their own anatomy.
Strap-ons aren't just for lesbian couples. The most common use scenarios:
- Pegging: A woman anally penetrates a man with a strap-on
- Lesbian couples: Vaginal or anal penetration between two women
- Gender expression: Strap-on as part of body awareness, regardless of sexual partner
- Solo use: Strap-on attached to the thigh or a surface for hands-free experiences
The three components: what you need
Component 1: The Harness
The harness secures the dildo to the body. Two main types:
- O-ring harness: An interchangeable ring holds the dildo. Advantage: you can use different dildos with the same harness – as long as the dildo has a suitable suction cup base. Recommended for beginners.
- Closed harness: The dildo is permanently integrated or in a fixed opening. Less flexible, but more stable fit.
Size: Harnesses are usually adjustable. Measure your hip circumference before buying – most harnesses fit hip circumferences of 60–120 cm.
Component 2: The Dildo
Not every dildo is harness-compatible. Prerequisite for an O-ring harness: a flat, wide base (suction cup base) that is larger than the O-ring diameter. The dildo must pass through the ring, and the base must hold behind it.
Important: O-ring diameter and dildo shaft diameter must match – too much play = unstable fit, too tight = difficult insertion.
Component 3: Lubricant
Water-based lubricant – always. Silicone-based lubricant reacts with platinum silicone and permanently damages the surface. Prefer gel consistency – lasts longer than thin lubricant.
Putting on the harness: Step by step
Step 1: Check O-ring size. The shaft diameter of the dildo determines the O-ring. Rule of thumb: O-ring inner diameter = dildo shaft diameter ± 0.5 cm.
Step 2: Thread the dildo through the O-ring – from front to back. The base of the dildo rests behind the ring on the inside of the harness.
Step 3: Put on the harness and adjust the straps. The harness sits on the hips, not the waist. Too loose = dildo wobbles. Too tight = restricted movement.
Step 4: Check fit. Gently push the dildo downwards – it should not slip out of the ring. Test hip movement – the harness should not slip.
Step 5: Apply lubricant to the dildo – generously, before use begins.
Choosing the right dildo for strap-on use
| Parameter | Beginner recommendation | Reasoning |
|---|---|---|
| Length | 12–16 cm usable | Shorter than you think – the wearer feels no resistance, controlling depth is more difficult than with manual use |
| Diameter | Ø 3–4 cm | Vaginal: Ø 3.5–4 cm. Anal (Pegging): Ø 3–3.5 cm. Both scenarios: start slimmer |
| Shore hardness | Shore 20–28A | Firmer than for solo use – the wearer needs resistance to control depth and angle. Too soft = uncontrollable movement |
| Base | Suction cup base (flat, wide) | Mandatory for O-ring harness compatibility |
| Shape | Realistic or slightly curved | Slight curve facilitates prostate stimulation during pegging |
First positions for beginners
Position 1: Doggy Style (recommended for beginners)
The receiving person in doggy position, the wearer behind them. Easiest control over depth and angle – the wearer sees what's happening and can precisely control pace and depth. Recommended for the first time with a strap-on.
Position 2: Missionary Position
The receiving person on their back, the wearer on top. Eye contact possible – good for communication during use. Requires a bit more coordination than doggy style, but a more natural body posture for the wearer.
Position 3: Side-by-Side
Both people on their sides, one behind the other. Less effort for the wearer – suitable for longer sessions. Less depth control than doggy style.
Position 4: Thigh Strap-On (Solo or Couple)
Harness attached to the thigh instead of the hips. The receiving person rides on the thigh – hands-free for both people. Also suitable for solo use.
Communication & Safety
The wearer feels no direct resistance – no feedback on depth or pressure. This makes communication during strap-on use more important than with other toys.
- Before use: Agree on a safe word. Discuss pace and maximum depth. Have lubricant ready.
- During use: Provide regular feedback – the wearer cannot assess pressure and depth themselves. Reapply lubricant regularly.
- For pegging: Anal preparation is mandatory – lubricant, slow insertion, no pressure. The receiving person sets the pace.
Why platinum silicone is the only standard for strap-on dildos
At SilikonLust, every strap-on dildo is hand-poured – made from 100% platinum silicone, without fillers, without compromise on material. This is not a marketing statement. It is why the experience with a SilikonLust toy is different.
Hand-pouring instead of machine production
The liquid platinum silicone is manually poured into the mold – layer by layer, with precise control. The result: no casting seams at the O-ring contact point, uniform Shore hardness across the entire shaft, complete reproduction of every design detail. A toy that feels as it was designed – not like a compromise from mass production.
Platinum silicone: the material that makes the difference
Platinum silicone is non-porous, odorless, and completely sterilizable. For shared strap-on use – between two people or between vaginal and anal use – this is crucial: boil at 100°C, complete sterilization, no bacterial residue on the surface. TPE cannot do this. Platinum silicone can.
The experience only platinum silicone delivers
Platinum silicone adapts at body temperature – it becomes softer, silkier, more natural. The Shore hardness remains constant, but the haptics change. This is the difference between a toy that feels alien and one that feels right. SilikonLust develops strap-on dildos with this claim: the most realistic, comfortable, immersive experience – through material and craftsmanship, not through marketing.
Cleaning after strap-on use
- Dildo after vaginal use: Warm water and mild soap, rinse thoroughly
- Dildo after anal use: Boil (100°C, 5–10 minutes) or medical disinfectant
- Dildo for shared use (two people): Complete sterilization – boil
- Harness: Hand wash with mild soap, air dry. Do not machine wash – straps and buckles can be damaged

Frequently Asked Questions
What dildo size for a strap-on?
For beginners: 12–16 cm usable length, Ø 3–4 cm, Shore 20–28A. Shorter and slimmer than you think – the wearer feels no resistance and finds it harder to gauge depth than with manual use. Start with a manageable size and gradually increase after positive experiences.
Do I need a special harness?
For beginners: an O-ring harness with interchangeable rings. Advantage: you can use different dildos with the same harness. Important: O-ring inner diameter must match the dildo shaft diameter. Most harnesses come with multiple O-ring sizes.
Can I use any dildo with a harness?
No. The dildo needs a flat, wide base (suction cup base) that is larger than the O-ring diameter. Dildos without a base or with a narrow base will slip through the ring. All SilikonLust strap-on dildos have an O-ring compatible suction cup base.
Strap-on for solo use?
Yes – two options: thigh harness (dildo on the thigh, hands-free riding) or attach a suction cup base to a surface without a harness. For solo use without a partner, the suction cup variant is simpler – no harness needed.
