To operate the Fleshlight, first remove the cap. Place an ample amount of water-based lubricant inside the artificial orifice (silicone-based lubricants can damage the finish on the Fleshlight material). Then insert your member. The amount of suction in the Fleshlight can be controlled by unscrewing the cap at the other end. When finished, remove the Fleshlight insert and wash it with warm water, but do not use soap. After every so often, apply corn starch to the Fleshlight insert to keep it fresh.
