Butt plug

Objects that are inserted into the rectum can therefore potentially travel up into the bowel; the flared end on a butt plug exists to prevent this.

For this reason, butt plugs tend to be shorter than dildos, and their marked size generally indicates the circumference of the device rather than the length.

Some plugs popular in animal roleplay have their tails molded from medical grade silicone as opposed to faux fur.

The firmness of the silicone, when combined with bodily movements or rhythmic pelvic-floor muscle contractions, allow for a simulated tail "wag".

[10] However, the flared flange is not a foolproof method of preventing the plug from entering the rectum completely with the inability to retrieve it.

Butt plugs of excess diameter can, especially when inserted too rapidly and/or too forcefully, lead to sphincter tear, detachment or other rectal failure.

When inserting a butt plug, one should be gentle, use plenty of lubrication, start with smaller sizes, and exercise patience.
