1. Charge it fully before first use and read the manual. Check whether it has a travel lock, so you know how to unlock it.
2. Wash it with lukewarm water and mild soap, or wipe it down if it isn't waterproof.
3. Put a drop of water-based lube on the tip. It makes the vibration softer and stops the skin chafing.
4. Start on the lowest setting and first hold it against a less sensitive spot, such as the labia or the inner thigh. Move closer to the clitoris gradually.
5. Try both the tip and the side. The tip gives a sharp, pinpoint sensation; the side of the body a broader one. If it gets too intense directly on the clitoris, a thin layer of fabric or holding it against the clitoral hood can help.
6. Only increase the intensity or change pattern once your body has got used to it. Many bullets only step forwards, so learn the order before it matters.
7. Switch off, clean it and let it dry completely before you charge it or put it away.
