please help......(warning!! this has sexual content)

my boyfriend are deeply in love we're fiancées ....
and well sex is amazing ....but the only problem is he wont go down on me but yet ill give him a blowjob willingly ...now the issue isn't the fact that he doesn't want to, he wants to just he cant stand the taste...he says the taste of any cum or the smell of cum turns him off ...but he'd willingly go down if it would all be masked...we tried every flavored lube out there...please help i want that pleasure .... i'm a bisexual girl and he told me "go ahead and get a girl bc i wont go down unless its all masked"....but you see i dont want to do tht bc i really care about him and only want him in my life!...so if you can please let me kno what i can do to help him so he can pleasure me....
