Put 'em in -- and leave 'em in. These anal plugs come in variety of sizes because not all butt plugs are made equal, but they all have a similar shape, narrow at the base, thickens in the middle and narrowest on top. The flared base prevents the anal plugs from getting "sucked in" and lost inside. Anal plugs are designed to stay in place rather than be pushed inside and out. We carry beginner anal plugs and various vibrating butt plugs for his and her pleasure.
