Condoms

Size refers to width

You don’t choose a condom based on length, but on its nominal width, indicated in millimeters on the package: this is half the circumference when laid flat. The standard size ranges from 52 to 54 mm. If it’s too narrow, it’ll be too tight and might break; if it’s too wide, it’ll slip off. Many people who “don’t like condoms” have simply never tried the right width.

What makes them ineffective

Three things—and they’re all avoidable. The expiration date: aged latex becomes brittle. Oily substances—oil, petroleum jelly, massage cream—which break down latex in a matter of minutes; only water-based or silicone-based lubricants are compatible. And using two condoms at once, which causes them to rub against each other instead of doubling the protection.

Sensations and Durability

Thinner models provide greater sensation without compromising protection: the safety standards are the same. Latex-free options are available for those with allergies and conduct heat better. Textured or scented versions are a matter of personal preference. Store the boxes away from heat and light—not in the glove compartment or wallet, where friction will eventually wear down the packaging.
