A thin, flexible shield for the mouth to protect against transmission of STDs (Sexually Transmitted Diseases) during cunnilingus and oral-anal sex. A shield (32) is held over the mouth either alone or in a holder assembly (44) by mounting devices which retain the mask against the face of the user. The holder assembly (44) may consist of one or two rings (30U, 30L) interlocked with each other or with the shield to grip the shield.
