The essentials
Crazy Bull Bertram: what you need to know before you buy
Is it for you?
Who the Crazy Bull Bertram is for, and who it isn't
It suits you if…
- You want a simple cock ring with no motor or battery.
- You want a flexible ring rather than a rigid one (this one is).
- You like the idea of a textured outer face.
- You prefer something light, at 44 g.
Better look elsewhere if…
- You want it to vibrate. This one has no motor.
- You want to use it in the bath. It is only splashproof.
- You are allergic or sensitive to silicone.
Step by step
How to use the Crazy Bull Bertram
- Wash it before first use with warm water and mild soap.
- Put a little water-based lubricant on the ring and on the penis so it slides on without pulling the skin.
- Place it at the base of the penis slowly, ideally before the erection is complete.
- Take it off by stretching it gently as soon as you finish, or if you feel any discomfort.
Cleaning
Clean with warm water and mild soap before and after each use. Dry it well with a clean towel and store it away from other toys.
Our tips
- Take it off straight away if you feel pain, coldness or tingling, or if the skin changes colour.
- Do not wear it for long periods at a time, and do not fall asleep wearing it.
- If it already feels too tight when you put it on, do not use it.
- If you take anticoagulants or have circulation problems, talk to your doctor first.
- Do not use silicone-based lubricant: it can damage the material.
