A dildo is a sex toy primarily designed for sexual stimulation, typically resembling a phallus (penis). It is often made of various materials such as silicone, rubber, or other body-safe materials. Dildos are used for both solo and partnered sexual activities and can be used for vaginal or anal penetration, depending on the design and intended use. They come in various sizes, shapes, and textures to cater to different preferences and fantasies. Dildos are a common tool for exploring one's own body, enhancing sexual pleasure, and can be a part of a healthy and consensual sexual experience for adults.
