Using an expired condom is not recommended because the material of the condom degrades over time, making it less flexible and more likely to break or tear. This increases the risk of contracting sexually transmitted infections or getting pregnant. However, if you have no other option, using an expired condom is still better than not using one at all. If the expired condom was stored in a cool, dry place, it may work better than nothing. It is best to store unused condoms in a cool, dry place where they wont get creased or dried out. If a condom ever seems dry, sticky, or stiff when it comes out of the package, it should not be used. It is also important to note that oil-based lubricants such as lotion, massage oil, mineral oil, petroleum jelly, or baby oil should not be used with condoms because they can break down the material. In summary, it is best to use condoms before their expiration date and to store them properly to ensure their effectiveness.
