Please help with mid-temp song

I heard part of a song the other day and would greatly appreciate any assistance so that I can buy it. The song was sung by a female, but the chorus featured additonal vocals. The female sings about the things she wants to do for her mate(nothing kinky). She sings " I wanna ..."
One of the the things is "I want to be the perfect wife." I know this is not a lot of information, but any help would be appreciated. By the way, this is an R & B song. Thanks in advance.

I caught the end of a mid-temp song and would love to know who the artist/title of the song is. Any assistance would be appreciated. It's an R & B song sung by a female who describes the things she wants to be for her mate. The lyrics that I remember are as follows:

I wanna do for you.....
I wanna be the perfect wife



I know this is not alot to go on, but all help is appreciated. Thanks in advance.
