Anal dildos and vibrators are specially designed for anal use. They are ergonomically designed to fit with ease and comfort, with a tapering shaft that can vary in size and shape. Unlike butt plugs they can be used for penetration mimicking anal sex, although lubrication is a must to avoid any discomfort and pain. When using an anal dildo for the fist time it is recommended to choose a smaller model and be gentle to avoid any anal fissure or other complications, take time to make sure you are relaxed and take it slow and gentle.
There is a whole host of sizes from small and sleek for the first time user to the larger models, with a range of materials from soft jelly to hard smooth Pyrex glass. Vibrating models allow for extra stimulations with soft or intense vibrations. Always chose a suitable lubrication for the toy you choose.
