The blue b-Vibe Butties Bulb Silicone Prostate Plug is a compact manual plug with a rounded angled head shaped for prostate-directed pressure. It has no motor, battery, remote, or app. Sensation comes from the bulbous profile, body position, and controlled movement. The super-soft seamless silicone exterior leads into a slender neck and a wide external finger-ring base.
Compact bulbous profile
- Insertable length: approximately 3 inches
- Total length: approximately 4.2 inches
- Maximum diameter: approximately 1.3 inches
- Base thickness: approximately 2.5 inches
- Material: seamless silicone
- Power: none; fully manual
The head widens gradually and then narrows into the neck. Once positioned comfortably, the neck reduces bulk at the opening while the external base stays accessible. The ring gives the hand a positive grip during insertion or removal. It is a retrieval feature, not a cock ring or suction cup, and the product should never be inserted past its base.
Bulb versus angled-tip designs
The Bulb concentrates fullness in a short rounded head. The b-Vibe Butties Hither Prostate Plug is longer and uses a more pointed come-hither tip. The b-Vibe Thumb Silicone Prostate Plug offers another compact manual shape. Shoppers who prefer powered stimulation can compare the b-Vibe Essential Vibing P-Spot.

The Bulb’s 3-inch insertable length does not automatically make it comfortable for every beginner; diameter, firmness, anatomy, and experience all matter. Compare it with a familiar toy and read our prostate-toy buyer guide and beginner sizing guide.
What a short manual plug changes
A shorter insertable length can make the ring easier to reach and can reduce the amount of shaft inside the body, but it does not eliminate the need for slow preparation. The 1.3-inch bulb is the widest point, so the transition over that section will be more noticeable than the narrow neck that follows. Unlike a vibrating model, the Bulb stays quiet and does not require charging. Unlike a remote-controlled plug, it cannot be activated by a partner from a distance. Its strength is direct, predictable geometry: the user can angle the head, hold it still, or make small deliberate movements.
The ring base is designed for retrieval and hand control. Do not hang weights from it, attach improvised cords, or use it as a substitute for a harness connection. If the ring presses uncomfortably against the body, remove the plug and change position instead of continuing through pressure. The product should remain easy to remove at all times and should not be used when reduced sensation, alcohol, medication, or a numbing product would make physical feedback harder to interpret.
Preparation and controlled use
Apply generous water-based lubricant to the plug and body. Begin in a position where the ring remains easy to reach. Guide the tapered head slowly, pause when muscles tighten, and never force the widest section. Once inserted, small changes in pelvic angle or gentle movement can shift where the bulb applies pressure. A manual plug will not produce automatic thrusting or vibration. The prostate massager use guide covers pacing, positioning, and stop signals.
Partner use and barriers
During partnered play, the receiving partner should control pace and communicate any change in comfort immediately. Agree on a stop signal before insertion and keep the ring visible. If the toy is shared between people or body areas, use a fresh compatible barrier for each person or transition and follow a complete cleaning routine. A barrier does not replace lubrication or inspection. Avoid moving an anal toy to another body area without changing the barrier and cleaning it appropriately.
Waterproof care and storage
The manufacturer describes the silicone plug 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 around silicone. Store the plug separately in a clean, dry pouch or container so the surface does not collect lint or remain pressed against another toy material. See our lubricant guide, cleaning and storage guide, and materials and care page.
Inspect the silicone, neck, base, and ring before every use. Do not use it if you find tears, cuts, tackiness, or deformation. Stop for sharp pain, bleeding, persistent numbness, or loss of sensation. Opened intimate products may have hygiene-based return limits; review the returns and hygiene policy before opening.
