         Do you and your sex partner know each others' tests
         results for a VARIETY of sexually transmitted
         infections including human immunodeficiency virus?
         
         Will you and next potential sex partner get tested
         TOGETHER for a variety of sexually transmitted
         infections including human immunodeficiency virus and
         share the results with each other BEFORE having sex?...
