Choose the tail before the Interchangeable Tail Butt Plug Base enters the scene, then let your partner make the final connection. A firm snap joins the outside connector to a matching attachment, so the insertable fit stays familiar while the role changes above it. The tail is sold separately, making this plug base useful when building a matching system or replacing its insertable part.
Note: One selected plug base is included; the tail attachment is sold separately. Small is the Beginner-Friendly starting point, while Large and Extra Large are Intermediate choices for users comfortable with wider plugs. Each size is sold separately, and the flared base stays outside the body as the stopper and removal grip.
