Put 'em in -- and leave 'em in. These anal plugs come in avariety of sizes because not all butt plugs are made equal, but they all have a similar shape, narrow at the base, thickening 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.
Anal beads are meant to come out. Many men and women enjoy the feeling of the anus opening and closing around each anal bead during orgasmic contradictions. We recommend that you pre-insert a strand of lubed anal beads and then slowly pull them out during orgasm for the maximum pleasure.
