Prostate Collection Expand Plug by B-Vibe

The Prostate Collection Expand Plug by B-Vibe is a remote-controlled anal plug that expands inside you across five diameter levels while delivering five vibration patterns. It lets you customise the fit to your body and adjust intensity without interruption, making it suited to men exploring deeper prostate sensation and couples wanting wireless control over shared play.

What it is and how it's made

The Prostate Collection Expand Plug by B-Vibe is a remote-controlled butt plug engineered around one core innovation: an expanding chamber that grows inside you. The plug begins narrow for easy insertion, then inflates across five distinct diameter levels when you press the remote. This mechanism means it adapts to your body's readiness and your arousal in real time, rather than staying static like conventional prostate toys. The body is formed from medical-grade silicone—soft, hypoallergenic, and made to flex gently as it expands.

Built into the expanded head is a vibration motor with five separate patterns, so expansion and sensation work together. The wireless remote gives you complete control without interrupting the experience. The silicone is non-porous, easy to clean, and durable enough for regular use. Its weight and profile make it manageable during hands-free wear.

The features that matter

• Five expansion levels: Start at a narrow diameter for insertion, then grow step by step to 1.5 inches maximum, letting you find your exact comfort zone.
• Five vibration patterns: Choose from distinct pulse sequences and adjust them independently of expansion for layered, customisable sensation.
• Wireless remote control: Operate the plug from up to 30 feet away, letting you or a partner change intensity without pausing or repositioning.
• Medical-grade silicone: Non-porous, hypoallergenic body that sits soft against sensitive tissue and resists discolouration or odour over time.
• Hands-free design: Once inserted and expanded, the plug holds itself in position, freeing you for movement, partnered activity, or solo focus.

Specs in full

• Insertable length: 3.5 centimetres; base width accommodates most body types without excessive bulk.
• Maximum diameter: 1.5 inches (approximately 38 millimetres) at full expansion; minimum diameter approximately 1 inch (25 millimetres) for insertion.
• Weight: 3.2 ounces (91 grams), lightweight enough for extended wear without fatigue.
• Material: Medical-grade silicone throughout; non-porous and free from phthalates or BPA.
• Power source: Rechargeable battery; wireless remote with replaceable button-cell batteries included.
• Box contents: Plug, wireless remote, USB charging cable, and instructions.

Preparation and first use

Before first use, wash the plug thoroughly with warm water and mild soap, then dry completely. Charge the battery fully using the included USB cable; a full charge takes approximately two hours. Familiarise yourself with the remote by testing expansion and vibration patterns while the plug is in your hand so you understand how each button works. Read the instructions to confirm your comfort level with the range of sensations.

Begin by applying a generous, water-based lubricant to the plug and to yourself; the narrow starting diameter makes insertion straightforward, but adequate lubrication makes the experience smoother. Insert the plug slowly, then start on the lowest expansion level to let your body adjust. Once settled, experiment with the vibration patterns before increasing expansion. Never move directly to the highest level in a first session; most people benefit from gradual warm-up and exploration of P-Spot Plugs to understand their personal sensitivity and preferences.

Who should buy it

Care and storage

After each session, wash the plug under warm running water with a mild, fragrance-free soap, paying close attention to the base and seams where bacteria can hide. Dry it completely with a soft cloth before storage. Store in a cool, dry place away from direct sunlight and heat sources. Clean the remote with a dry cloth; do not immerse it in water. Keep the battery in the remote if you use it regularly, or remove it if storing for extended periods to prevent corrosion.

What to expect

The expanding mechanism creates a sensation fundamentally different from a static plug. At lower expansion levels, you feel gentle pressure; as diameter increases, that pressure intensifies and shifts toward deeper internal contact. The vibration motor sits in the expanded head, so higher expansion levels also amplify how strongly you sense vibration. Most people find levels one and two comfortable for warm-up; levels three to five are where serious prostate targeting happens.

First-timers often underestimate how gradually to introduce expansion. Your body needs time to adjust to each level, and rushing defeats the purpose of the customisable design. Pairing expansion with vibration creates layered sensation—try low vibration at high expansion, or high vibration at low expansion, to discover what your prostate responds to. Sessions typically last 20–45 minutes; beyond that, fatigue or numbness may set in.

Cleaning is straightforward because silicone resists staining, but the seam between the base and expanding chamber traps moisture if not dried thoroughly. The remote is durable, but keep it away from moisture and high heat. Battery life on a full charge typically supports several sessions before recharging is needed. If you experience any discomfort beyond normal adjustment sensations, stop and allow recovery time before your next session.

How it compares

Why it's worth having

Pick up the Prostate Collection Expand Plug by B-Vibe if you want a toy that adapts to your body and your mood in a single session. The combination of expansion and remote-controlled vibration opens sensation possibilities that fixed toys cannot match. Expansion means you control intensity; vibration patterns keep sessions fresh. Unlike Steel Prostate Sex Toys, which offer firmness and weight, silicone expansion offers customisable, responsive sensation.
