A dildo is a sex toy that is designed to be inserted into the body for sexual stimulation. It typically has a phallic shape and can come in a variety of sizes, shapes, and materials, including silicone, rubber, glass, and metal. Dildos are used for both vaginal and anal penetration and are often used during solo masturbation or partnered sexual activity. They can be used for pleasure, sexual experimentation, or to simulate the sensation of intercourse when a partner is not available or desired. It is important to note that the use of sex toys, including dildos, should always be consensual and safe, and proper hygiene practices should be followed to prevent the spread of infections or other health issues.
