"He might be. He could be carrying the virus that cases AIDS. And you wouldn't even know it just by looking at him. He may not even know he has it. But if he does, he could pass it on to you. Without even knowing it. The AIDS virus is spread by blood and sexual intercourse.""Limit your risk by getting to know about your partner's past. He may have become infected years ago, before he even met you. Talk about AIDS and safer sex. Talk about your concern. If you decide to have sex, use condoms and spermicide. Remember, you are responsible for protecting your own health -- nobody else is.""Developed by AIDS Research & Education Project, California State University -- Long Beach, (213) 985-7508.""Designed by Roger Mejia.""Students for AIDS Facts and Education, with funding from the U.S. Centers for Disease Control and the Long Beach Health Department."
