A strap-on dildo is any insertable meant to ride in a harness. The shaft is only half of the system. The base has to lock to the harness so thrusting energy goes into a partner, not into slipping sideways.

Necks, Vac-U-Lock wells, and wide flares each pair with different harnesses. A beautiful sculpt with a soft, undefined base will flop. Length should consider the space the harness already occupies. What was a good handheld length can feel two centimeters longer once it is buckled on.

The wearer may want a grinder pad or a small inner bulb on their side of the harness. That is a separate piece for many setups. Talk about angle before the first thrust. A dildo that points at the ceiling when the wearer stands may point just right when they tilt their hips.

Pairing

• Match O-ring size to the neck.
• A backing plate saves the wearer’s pubic bone.
• Lube the partner, not the harness straps.
• Wash the dildo and the harness leather or elastic after.
