I think you’ve asked a great question and your interest in the ‘shelf life’ is really important, especially if you’re concerned about how long a shop has had a packet of condoms on sale for (I know some dodgy little shops I would never buy condoms from – I’m sure those packs have been on the shelf for a year!). If you’re comfortable that the stock at the place you’re buying from is ok, and the packs aren’t stored in full sunlight for months, definitely check those expiry dates.
How long have you had the condoms you’re worried about? And, more importantly, where do you normally store them? There’s some great tips in the article Nurse Nettie has shared but don’t forget keeping a condom in your wallet for ’emergencies’ isn’t always a good idea, especially if you leave it in there for a long time. I like to think ‘fresh is best!’ 😉
