A dildo is a sex toy designed for sexual pleasure, typically shaped like a penis. They can be made from various materials, including silicone, glass, or rubber, and come in different sizes, colors, and textures. Dildos can be used for vaginal or anal stimulation and are often used by individuals or couples to enhance sexual experiences. Many dildos are designed to be phallic in shape, but there are also non-phallic options available. Some dildos may include features like vibration or suction bases for added stimulation. Users should always prioritize safety and hygiene by cleaning their dildos properly and using appropriate lubricants.
