A flared-base dildo is a term for a type of sex toy with a phallic shape and wide, flat base. These dildos are usually made from "rubbery" materials like silicone or jelly, but they can be manufactured from a variety of substances including glass or stainless steel.
Like other dildos, the body of a flared-base dildo is longer than it is wide and insertable. This tapered shape is ideal for vaginal and anal penetration. However, its flat base sets it apart from other dildos. The bases of flared-base dildos take a variety of shapes. Flared-base dildos with T-bars, suction cups, large rings, and testicle-shaped mounds are all common. The wide base prevents users inserting a flared-base dildo too far. It also provides something to hold on to for easier withdrawal after deep penetration. This is vital for anal penetration, as the anus can suck sex toys deeper inside than intended especially when the muscles contract during orgasm.

You may attach the flat base of a flared-base dildo to other sex toys such as strap-on harnesses or sex machines and consoles. People may attach a flared-base dildo to a sex harness for vaginal and anal strap-on sex. Using a flared-base dildo in this way lets people without penises penetrate their partner. Using a flared-base dildo, rather than a double-ended dildo, is a great option for people new to pegging, as it allows the giving partner to focus on their receiving partner’s pleasure, without the distraction of being simultaneously penetrated. Attaching a flared-based dildo to a sex machine or furniture designed to hold a dildo can add variety to solo or couples play.
You could also use a flared-base dildo on its own for penetration or clitoral stimulation. People may use their flared-base dildo in this way on their own or with a partner. Some people may enjoy watching their partner use the dildo on themselves. Others enjoy taking control and penetrating their partner with a flared-base dildo they manipulate by hand. This gives them greater control of the depth and angle of penetration. You might attach a flat-based dildo with a suction cup to a flat, smooth surface, such as a table, wall, or sex toy mount, for hands-free stimulation.
