The blue b-Vibe Butties Sleek Tapered Silicone Plug is a manual training plug with a long gradual taper instead of a short bulb or abrupt step. Its rounded tip begins narrow and widens progressively to approximately 1.3 inches before narrowing toward the base. A broad external base and finger-sized retrieval ring remain outside the body for control and removal.
Long gradual training profile
- Insertable length: approximately 4.6 inches
- Total length: approximately 5.8 inches
- Maximum thickness: approximately 1.3 inches
- Base thickness: approximately 2.5 inches
- Material: seamless silicone
- Power: none; fully manual
The taper lets the user control progress in small increments rather than crossing a single large bulb. That does not make the full length or width appropriate for every user. Insert only to a comfortable depth, pause when muscles tighten, and never treat the maximum measurement as a target. The product has no motor, vibration, remote, or app connection; sensation comes from gradual stretch, fullness, pressure, and deliberate movement.
Compare the Butties shapes
Sleek emphasizes a long progressive taper. The Butties Bulb Prostate Plug places a wider rounded head on a shorter 3-inch insertable length. The Butties Hither Prostate Plug uses an angled come-hither tip for more directional pressure. For a smaller first step, compare the Rookie Beginners Starter Plug. Browse all butt plugs and trainers for additional sizes.
A trainer is useful only when its dimensions match the user’s current comfort. The beginner sizing guide explains why diameter and progression matter more than labels such as beginner or advanced. If prostate-directed pressure is the goal, the butt plug versus prostate massager guide distinguishes a gradual fullness profile from an angled target shape.
Using the taper as a progression tool
The long taper lets the user stop before the widest section instead of making insertion an all-or-nothing step. Mark progress by comfort and control, not by depth. Hold the plug at a comfortable point, allow muscles to relax, and withdraw slowly before fatigue develops. On another session, the same point may feel different; never assume that reaching a depth once means it must be repeated. A training plug is not a medical dilator and should not be used to treat pain, injury, or a health condition without guidance from a qualified clinician.
The external ring can help keep orientation consistent while the shaft moves through the gradual taper. Keep one or two fingers through or around the ring rather than letting it become trapped against the body. If the base begins to tilt, pinch, or disappear between the cheeks, remove the plug and reassess position. Do not sit on a hard surface in a way that forces the base into the body.
Preparation and controlled progression
Apply generous water-based lubricant to the full portion that may contact the body. Choose a position where the ring remains easy to reach, begin with the narrow tip, and advance only while the body stays relaxed. Hold at a comfortable point before moving farther. If resistance increases, withdraw slightly and add lubricant rather than forcing the shaft. Avoid numbing products because pain and sensation are important feedback.
The ring is a retrieval and control feature. Do not attach weights, cords, or improvised accessories to it. The plug should remain easy to remove at all times and should not be used when alcohol, medication, numbness, or reduced sensation would interfere with feedback. During partnered use, the receiving partner should set the pace and have an immediate stop signal.
Waterproof cleaning and storage
The manufacturer describes Sleek as fully waterproof. Wash it before and after use with warm water and mild unscented soap or a compatible toy cleaner, rinse thoroughly, and dry completely. Use water-based lubricant as the conservative default for silicone. Store separately in a clean, dry pouch or container. See the water-based lubricant guide, cleaning and storage guide, and materials and care page.
Inspect the tip, shaft, neck, base, and ring before each use. Stop for sharp pain, bleeding, persistent numbness, or loss of sensation. Opened intimate products may have hygiene-based return restrictions; review the returns and hygiene policy before opening.
