Strap-On Sex: What It Is and How to Get Started
A strap-on is a harness worn around the hips (or sometimes the thighs or face) that holds a dildo in place for penetrative sex — used regardless of the wearer’s own anatomy. It’s one of the most straightforward ways to add penetration to a same-sex encounter, an opposite-sex encounter where the receiving partner is male, or any dynamic where neither partner has anatomy that would otherwise allow for it.
How the gear works
A strap-on setup has two parts:
- The harness — typically leather, fabric, or a silicone-lined material, worn around the hips with adjustable straps. Some harnesses are designed for thigh or face wear instead, for different positions or preferences.
- The dildo — usually silicone, chosen separately from the harness in most systems so the size and shape can be swapped based on preference or the receiving partner’s comfort.
Most beginner-friendly harnesses use a universal ring system that fits a range of dildo bases, so you’re not locked into one specific dildo once you own a harness.
Common uses
Strap-ons show up across a wide range of dynamics:
- Between two women, or any couple where neither partner has a penis, as a way to add penetration.
- In pegging — a woman using a strap-on to anally penetrate a male partner, which has become common enough to be its own frequently searched term.
- As part of broader D/s dynamics, where a strap-on can reinforce a specific power exchange regardless of the partners’ anatomy.
Choosing a first strap-on
For a first purchase, harness comfort matters more than the dildo itself — an uncomfortable or poorly adjusted harness is the most common complaint from beginners, far more than dildo size or shape. Look for a harness with genuinely adjustable straps, a comfortable material against skin for extended wear, and pair it with a smaller, softer dildo to start, sizing up later once you know what’s comfortable.
Getting started comfortably
Plenty of lubricant, a slow start, and clear communication about pace and depth make the biggest difference in comfort for the receiving partner — far more than the specific gear chosen. It’s worth practicing putting the harness on and adjusting it before a scene, rather than fumbling with straps in the moment.

Frequently asked questions
- Do you need a specific body type to use a strap-on?
- No — that's the entire point. A strap-on lets anyone, regardless of anatomy, wear a dildo in a harness and use it for penetrative sex. They're used across same-sex and opposite-sex couples alike, and by individuals of any gender.
- What's the difference between a strap-on and pegging?
- A strap-on is the equipment (harness plus dildo). Pegging specifically refers to a woman using a strap-on to anally penetrate a male partner — one common use case for the gear, not the only one.
- What should a beginner look for in a first strap-on?
- A comfortable, adjustable harness is more important than the dildo itself for a first purchase — an ill-fitting harness is the most common source of frustration. Look for adjustable straps, a comfortable base material against skin, and a dildo on the smaller, softer end to start.
- Is strap-on sex uncomfortable for the receiving partner?
- It shouldn't be, with the right size, plenty of lubricant, and a slow start — discomfort is usually a sign of rushing, insufficient lubrication, or a size mismatch rather than something inherent to strap-on sex itself.
- How do you clean a strap-on?
- This depends on material — most silicone dildos can be washed with mild soap and water or a dedicated toy cleaner, while harnesses (especially leather ones) usually need to be wiped down rather than submerged. Check the manufacturer's care instructions, since materials vary.
