I've got a question for you.  If a provider is couples friendly, she's got to be legitimately bi right?  I've heard of two providers being able to "fake it" with a guy and not really mess with each other if DATY really wasnt their thing.  However, with a couple a provider has a job to satisfy two people,  provided that the she in the couple wanted some DATY.  Would like to hear everyones two cents.
