This website sponsored by the Idaho state government (I know, right??) also offers some good solid advice about condom use. Their take on expired condoms is that, because they can break more easily, it’s best not to use them. But they also offer other tips on using condoms effectively.
I know, I know. You’ve been using these things since you were four (or so it may seem) and you know what you’re doing but hey, sometimes we get stuck in our ways and refuse to change how we do things. So brush up on your rubber skills!
OK, here’s one you may not have thought of. Opening the package, it turns out, should be done in a calm and humble fashion; in other words, don’t use your teeth, Casanova! Not only can you tear the condom this way, you might also get a nasty taste of spermicide which can spoil the mood and make your tongue all tingly (not in a good way).
Remember, also, to use only water-based lubricants. Although they're okay for when you're on your own, baby oil, olive oil, petroleum jelly, hand lotion or anything with an oil base can weaken latex and make a condom more likely to break. Spring for some lubricant meant for use with condoms, or spend more time on foreplay. Applying a drop of lube into the tip of the condom before putting it on can also help prevent breakage if things get a bit, uh, frisky.
Now go forth, be safe, and have fun!
