Butt plugs come in all shapes and sizes. Beginners should start small in picking their first anal toy and then  graduate to medium and then big butt plugs or even huge. This all depends on the person and how much they can handle. All butt plugs are made from a variety of non-porous materials that are easy to lubricate and clean.   Pick a butt plug that looks like you can handle it for the first time. Then move up!
