Oral Dams, oftentimes called dental dams, are a thin sheet of natural latex designed to prevent the
exchange of bodily fluids during oral sex. Because HIV and STDs have been found
to exist in the vaginal fluids and menstrual blood of infected women, it is
recommended that a latex barrier be used between the mouth and the vaginal area
when cunnilingus (oral-genital contact) with a woman is being performed. When
used properly oral dams can help reduce the risk of contracting STI’s during oral sex.
