The essentials
Mystim The Earl 51 mm: what you need to know before you buy
Is it for you?
Who the Mystim The Earl 51 mm cock ring is for
It suits you if…
- You want a firm metal cock ring that looks like a piece of jewellery.
- You've measured yourself and your diameter is around 51 mm.
- You prefer a rigid ring that maintains pressure without stretching.
- You want something simple, with no batteries or charging.
Better look elsewhere if…
- It's your first cock ring and you don't know your size. A stretchy silicone ring is more forgiving if you get the size wrong.
- Your measurement is well above or below 51 mm. As the ring is rigid, it won't apply pressure if it's too big, and will be too tight if it's too small.
- You want a vibrating cock ring. This is simply a steel ring.

Our usage tips
How to use the Mystim The Earl 51 mm cock ring
- Measure yourself. Wrap a measuring tape around your testicles and penis, bringing the ends together at the top, close to your body. Adjust it until it feels comfortable, mark where the ends overlap and measure that length in millimetres.
- Divide by 3.14 using the circumference you've measured. The result is the diameter you need. Measure again on several days and at different times, as your measurement varies.
- Put it on before an erection. Pass your testicles through the ring first, then your penis.
- Check the fit. It should feel snug, without pain or discomfort.
- Take it off before 30 minutes are up. If it's difficult to remove, use water-based lubricant to help.
Cleaning
Wash it before and after use with lukewarm water and mild soap, rinse thoroughly and dry with a cloth before storing.
Our advice
- Don't wear it for more than 30 minutes at a time or fall asleep with it on.
- Remove it immediately if you notice pain, coldness, tingling or a change in skin colour.
- If you're between two sizes, choose the larger one, especially if it's your first cock ring.
- If you're allergic to any metal, seek advice before using it.
- If you can't remove it, don't pull hard. Seek medical help.
