C-shaped vibrators hook into the vagina and curve forward so one arm rests on the clitoris while the inner arm presses toward the G-spot. Worn during penetrative sex, they add a third point of contact without anyone holding a wand.

The inner arm has to stay put when a partner moves. Too slim and it slips. Too thick and it crowds the shaft. Couples often need a minute of awkward grinning and repositioning before the geometry clicks. Lube on the inner arm helps it seat; too much on the outer arm makes it skate off the clitoris.

Motors may live in one arm or both. App and remote versions are common because hands are already busy. Afterward, wash both arms and the hinge zone. That inner crease collects lint.

Making it work

• Insert the inner arm first, then settle the outer pad.
• Try positions that keep pelvises close; long-distance thrusting can dislodge it.
• Charge before partnered use so the motor does not fade mid-scene.
• If the toy has a magnet charger, dry the contacts or it will not dock.
