Dildos, vibrators, and other Clitoral suction sex toys are sometimes called "discreet." Why? Because they can look like other things. For instance:A dildo is a phallus used for penetration during sex play. It might be made of silicone or rubber (a type of rubber), plastic, glass and more. They come in all shapes, sizes and colors -- but not always the same color as this battery-powered version below!Vibrators (sometimes called vibes) use vibrations to stimulate the body in many different places -- from your clitoris down to your thighs. You can purchase them in many different colors such as pink or purple if you want something that looks more fun than black or white (like this cordless bullet vibe).
