Who should use a condom?

A person who takes part in risky sexual behavior should always use a condom.

The highest risk comes from having intercourse -- vaginal, anal, or oral -- with a person who has a sexually transmitted disease. If you have sex with an infected person, you're taking a big chance. If you know your partner is infected, the best rule is to avoid intercourse (including oral sex). If you do decide to have sex with an infected partner, you should always be sure a condom is used from start to finish, every time.

And it's risky to have sex with someone who has shared needles with an infected person.

It's also risky to have sex with someone who had sex with an infected person in the past. If your partner had intercourse with a person infected with HIV (the AIDS virus), he or she could pass it on to you. That can happen even if the intercourse was a long time ago and even if you partner seems perfectly healthy.

With sexually transmitted diseases, you often can't tell whether your partner has been infected. If you're not sure about yourself or your partner, you should choose to not have sex at all. But if you do have sex, be sure to use a condom that covers the entire penis to reduce your risk of being infected. This includes oral sex where the penis is in contact with the mouth.

If you think you and your partner should be using condoms but your partner refuses, then you should say NO to sex with that person.
