It’s not always about size, but sometimes it is.
Think about the condoms you and/or your partner normally use—that'll help narrow down which Ohnut will be most comfortable!
Classic: "Standard" or "regular" condoms; Lifestyles Snugger Fit, Slim Fit, or similar
Wider: Trojan Magnum, Durex XXL, or similar; or if a looser fit is preferred.
The Wider Ohnut is 15% wider than the Classic Ohnut and stretches up to 50% more.
All Ohnuts are made with a soft material that stretches significantly for comfort.
When in doubt about sizing, order the Wider Ohnut. It's unlikely to be too wide for effective use.
