What’s not to love about condoms? Not only are they 98% effective at preventing unwanted pregnancy, but they can also protect against most STIs including chlamydia and gonorrhoea.
But don’t let yourself be lulled into a false sense of security: condoms are only effective when used correctly, and when they are still in good working order.
An out-of-date condom, or one which has been damaged by heat or friction, is much less than 98% effective. Using an old or damaged condom will put you at serious risk of STIs and pregnancy.
Always check the expiry date, and make sure you store condoms in a cool, dry place. Your wallet is far from ideal, as your body heat and the friction from sitting on it will damage the condoms.
