Make sure that any foreign objects you insert into your vagina (such as tampons) are placed properly. Be sure to follow instructions on how long to leave it inside, how often to change it, or how often to clean it.
Not having sexual intercourse (abstinence) is the only absolute method of preventing sexually transmitted cervicitis. A monogamous sexual relationship with someone who is known to be free of any STI can reduce the risk. Monogamous means you and your partner do not have sex with any other people. See: Safe Sex
You can greatly lower your risk of catching an STI by using a condom every time you have sex. Condoms are available for both men and women, but are most commonly worn by the man. A condom must be used properly every time.
