What is the song title and artist for this song?

Question

I do not know the title or artist of this song. Please, help.
Here are a few words that I think I have made out of the song. It is a slow sweet song. R&B style. It's a man singing.

I need you to say it...I want to hear you say it... something?
On and on and on.

It repeats those lines a lot.

Thanks!
