First Brian McKnight shocked his fans with his now-infamous video of a piano-accompanied “iFUrReadyToLearn” where he sings “show me how your p***y works.” But, he later backtracked, claiming it was for comical relief and a lesson for the new generation, including R. Kelly and Chris Brown in Ebony Magazine. But TODAY! he show and proves once again. In a song written for the popular porn site, YouPorn, he sings of reasons why you need to head on over to the site. Like, if you need to escape from “sex in the city,” or have a little tingle for anal….. enough said. Peep the clip of the song courtesy of TMZ above.
