Exercises: The condom as dual protection

Explain what a barrier contraceptive method is, how a condom works, and how it differs from hormonal methods (pills, injections, implants) in terms of protection against STIs.

The condom is said to offer "dual protection". Explain what that expression refers to (prevention of pregnancy and of STIs) and why a person who uses contraceptive pills still needs a condom if they also want protection against STIs.

For a condom to be effective it must be used correctly. Order and explain these guidelines for correct use: store it in a cool, dry place; check the expiration date; use a new one every time; do not reuse it; open the package carefully, without tearing it. Also explain why using two condoms at the same time does NOT increase protection.
