Onyxxx Rechargeable Contoured Probe by California Exotics

Onyxxx Rechargeable Contoured Probe by California Exotics is a silicone butt plug designed for prostate stimulation with ten vibration speeds and a contoured shape that targets internal pleasure. Its rechargeable battery runs for up to 90 minutes, and the waterproof design works in or out of water. Built for men who want sustained, powerful internal stimulation.

The product itself

Onyxxx Rechargeable Contoured Probe by California Exotics is a silicone vibrator engineered to reach the prostate with precision. The contoured shape angles inward to target sensitive tissue directly, and the suction cup base sits flush against the body or locks into a harness. Unlike straight butt plugs, this probe's curves create focused stimulation rather than general pressure, making it purposeful rather than exploratory.

The build is solid silicone paired with durable ABS controls and a flexible suction base that grips firmly without sliding. A rechargeable battery powers ten distinct vibration speeds, from gentle pulses to intense waves, with a memory chip that returns you to your last-used setting automatically. This removes the need for battery changes mid-session and means no hunting through menus when you want to pick up where you left off.

Key features

• Contoured internal shape: Engineered angles target the prostate directly, delivering sensation exactly where internal nerves concentrate.
• Ten vibration intensities: Progressive speeds let you start gently and build toward stronger stimulation at your own pace.
• Waterproof design: IPX7 rating means you can use it during shower play, bath sessions, or water-based exploration without damage.
• Harness compatibility: The sturdy suction cup base attaches to harnesses or stands alone for hands-free use during partnered play.
• Memory chip technology: Automatically resumes vibration on your last chosen speed, skipping the cycle-through every time.

Preparation, use and clean-up

Before insertion, charge the probe fully using the supplied USB cable (2.5 hours for a complete charge). Apply water-based or silicone-based lubricant generously to both the probe and your entrance; the contoured shape benefits from extra glide on first use. Start at vibration level 1 or 2 to let your body adjust to the shape and angle. Once inserted, activate higher speeds gradually using the control buttons until you find the intensity that works for you.

The memory chip holds your last setting, so next time you simply switch on and begin. For cleaning, rinse under warm running water immediately after use and pat dry with a soft cloth. If you want a deeper clean before extended sessions, using enemas beforehand can give you extra peace of mind. Store in a cool, dry place away from direct sunlight, and keep the travel lock activated when packing for trips.

Right fit or not?

Care and storage

Rinse the silicone thoroughly under warm water immediately after use and dry completely with a lint-free cloth. Store in a cool, dark, dry place—a dedicated pouch or box away from other toys keeps it clean. Keep the travel lock engaged when packing for trips to prevent accidental activation. Do not expose to extreme heat or sunlight, which can degrade silicone over time. Check the suction cup monthly to ensure it grips securely; if it loses suction, a gentle wash and complete air-dry often restores it.

Combined with the contoured design of the Onyxxx, this knowledge shapes a confident, rewarding experience.

What to expect

First-time users often underestimate how much the contoured shape matters. The angle is not immediately obvious until the probe is inside and you switch on vibration—then the targeted sensation becomes clear. Most people find levels 1 through 4 are warm-up territory, level 5 or 6 is where sustained pleasure begins, and levels 7 through 10 deliver serious intensity. Do not rush to the highest speeds; the build-up is part of the experience.

The 90-minute battery life on low speed means you can relax into longer sessions without power loss mid-way. On high speed, 45 minutes is still generous—most people do not sustain level 10 for extended periods anyway. The memory chip removes friction; you tap the button and resume exactly where you left off, which is practical during solo sessions and especially useful in partnered play where switching hands or positions happens frequently.

Cleaning is straightforward because silicone resists odour and staining. A rinse under warm water and a quick dry is usually enough for regular use. The suction cup base stays secure on smooth surfaces like tiles or glass for hands-free play, though it loses grip on textured surfaces—something to know if you plan shower use on non-slip mats.

The contoured design does suit experienced users better than absolute beginners. Men who have already used straight probes and understand their own prostate sensitivity get on with this faster. Newcomers often benefit from a warm-up period with smaller toys first, simply because the 3.2 cm diameter and specific curve feel different from entry-level options.
