Dams (Dental Dam)

Posted in on

A thin, rectangular sheet of latex that is used as a barrier to prevent the transmission of sexually transmitted infections (STIs), including HIV. The dam is placed over the anus or vagina prior to oral sex or rimming to prevent body fluids being shared. Water-based lubricant is recommended to be used with dams, to prevent breakage. Dams should not be shared between sex partners – a new dam should be used for each sex partner.
