Using condoms is as much about protecting yourself as it is about protecting your partner(s).
Used correctly, condoms can prevent transmission of most sexually transmitted infections (STIs) including HIV.
Condoms come in different sizes. The width measurement of the base of a condom is usually shown in millimetres on a box of condoms. Try different sizes to find the one that fits you best.
Most condoms are made of latex but non-latex varieties (made from materials like polyisoprene or polyurethane) are also available. They can be sensitive and pleasure-enhancing, and are ideal for people who are allergic or sensitive to latex.
Lambskin or "natural" condoms do not provide reliable protection against HIV and other STIs and should not be used.
Good quality condoms display a kite mark and/or CE mark.
Condoms do go out of date, so always check the expiry date on the package.
