A strap-on harness is the belt system that holds a dildo against a body. Two-strap, three-strap, brief, jock, and corset styles all exist. The job is alignment and comfort. Everything else is fashion.

Hip straps should sit on bone, not on the soft lower belly where they slide. A crotch strap keeps the base from kicking upward. Too tight and the wearer goes numb. Too loose and the dildo nods. Leather lasts and needs care. Elastic is easy and stretches out. Nylon sits in the middle.

Try the harness with the actual dildo you plan to use. Walk. Squat. Thrust at the air. Hardware that looked sleek can bruise. Spare O-rings in two sizes save a night when the favorite toy does not match the favorite belt.

Fit checklist

• You should be able to slide two fingers under a strap after it is snug.
• Buckles on the side beat a single rear knot.
• Wash sweat out of linings.
• Replace frayed stitching before a scene, not during one.
