Who sings this song? "Oh, I get, so highh" (R&B)?

So i heard this song at the Post Office. It was kinda awkward cause
it's kinda like those bedroom scene songs! So now I'm curious cause
I'm bathroom singing this song out of nowhere Hahaha XD

Anyways, the song goes like; You know, i want you so bad, baby baby
baby or something like that. It's a woman singing and it sounds like
it's from the 90's... So yeah, let me know if you have any ideas!
