Using condoms every time you have oral, anal, or vaginal sex is the best way to reduce your chances of getting or spreading sexually transmitted infections. Condoms protect you and your partners from STDs by preventing contact with bodily fluids (like semen and vaginal fluids) that can carry infections. How To Insert and Remove a Female Condom Carefully open and remove female condom from package to prevent tearing. The thick, inner ring with closed end is used for placing in the vagina and holds condom in place. The thin, outer ring remains outside of body, covering vaginal opening.
