Strap-on Dildos

Strap-On Dildos: Wearable Penetration

Strap-on dildos are dildos worn via a harness, allowing the wearer to penetrate a partner regardless of natural anatomy. The category includes complete kits (harness + dildo together) and harness-compatible standalone dildos. Strap-ons are popular for couples wanting to swap penetration roles, for users who prefer wearable to handheld dildos, and for partners with anatomical or physiological constraints on penetration.

Most modern harnesses use either O-ring systems (the dildo passes through a sized O-ring, held in place by the flared base) or Vac-U-Lock systems (proprietary plug-in connection from Doc Johnson). O-ring systems are more universal; Vac-U-Lock is faster to swap but requires Vac-U-Lock-compatible dildos.

Frequently Asked Questions

What's the best strap-on for beginners?

The NewComers Pegging Kit is the standard beginner recommendation — designed specifically for first-time use, smaller size, beginner-friendly harness. For couples wanting more substantial size, the King Cock 6" or 7" kits are good entry-level options.

What size strap-on dildo should I get?

Smaller than you think. For first-time pegging or strap-on use, 5-6 inches insertable is appropriate. Larger sizes are less forgiving and harder for both partners. Once you've used a strap-on a few times, you can size up if desired.

How do harnesses fit?

Most strap-on harnesses are adjustable across a wide range of waist sizes. Quality harnesses use sturdy webbing or leather with multiple adjustment points. Test the fit while empty (no dildo) before adding the dildo — a poorly fitted harness shifts during use.

What's pegging?

Pegging is the act of a partner using a strap-on to anally penetrate another partner (typically used to describe a partner with a vulva penetrating a partner with a penis). The term is specific to strap-on anal penetration. Many strap-on kits market themselves as "pegging kits" to signal this use case.

What lube works with strap-ons?

Same lube rules as the dildo material: water-based for silicone dildos, silicone or water-based for non-silicone dildos. For anal use (pegging), silicone-based lubes generally work better — longer-lasting and slicker.
