condoms

Condoms are a way to protect yourself when you are having sex. They cover the penis and keep sperm from getting inside the vagina, so that a baby can't be made. Condoms are made of a thin, stretchy material called latex. They usually come with lube to make them easier to roll on. Using a condom every time you have sex is the best way to prevent pregnancy and protect yourself from getting STDs (sexually transmitted diseases).
