Kanye West -- I Gave My Future Spouse an Oral Exam ... And She Passed

It's a real oxymoron ... Kanye West realized Kim Kardashian was the girl he wanted to marry when she blew it.

A new remix for Beyonce and Jay Z's "Drunk in Love" was released Saturday featuring Kanye ... where Yeezus raps about stuff like Kim's ass and his least favorite sex positions.

But the craziest part ... Kanye flows about the first time he realized Kim could be his future wife -- saying, "I impregnated your mouth, girl, oooh ... that's when I knew you could be my spouse, girl."
