Frequently Asked Questions
Why is size so important?
A condom that's too big can slip off during sex, offering less protection. Too tight, and it becomes uncomfortable, can restrict circulation, and is more likely to break. The right fit = pleasure + safety.
What does "nominal width" mean?
It's the width of the condom when laid flat, unstretched. This is the industry standard measurement. To convert it to circumference: circumference = nominal width × 2. So 54 mm width = approximately 10.8 cm circumference.
I'm between two sizes, which should I choose?
Start by trying the larger of the two: a little too wide is still more comfortable than too tight. If you're torn between Standard and Large, most users find Large a better fit. You can also order an assortment pack to try several sizes at a lower cost.
