"tell me I'm your man."

I need help finding a song I hear today. It was sung by a guy who sounded pretty young, almost Justin Bieber-ish. It was a pop song and the only part of the lyrics I can remember is, "tell me I'm your man." Or maybe it was, "say that I'm your man." One of the two. Any help would be appreciated.

is it Bluff by Daphne Willis she sounds a lot like bieber.

I just checked that song out and it isn't it. I have a feeling it's a guy considering the lyrics are, "I'm your man." But it really sounds like a kid. Thanks for your help, though.
