help me with this song

I have had a melody in my mind for a week. I watched "Stepmom", where Julia Roberts and Susan Sarandon play, on TV on Sunday. In the movie, it is played a song which I listened to when I was a teenager. It is played in the middle of the movie ( between the middle and the end) and I think that the singers are the "The Boyz" or "NSync" or a male group like those ones. In the Scene, Julia Roberts is in her office sat down on her desk and somebody turns off the radioplayer and the music stops and she picks up the phone(if I am not wrong). The fragment is only 5-10 secs long. The song says something like "let me show you what it's all about....(I don't know what)...so baby come to me" and the verse ends up like that.

Please, help me. I don't know what else I can do. Even google has helped me!!!.

Thanksssssssss. :'(

Is it "WHEN THE LIGHTS GO OUT" by: Five?

This is the chorus and it repeats at least once each time

Baby, when the lights go out
Every single word cannot express
The love and tenderness
I'll show you what it's all about
Babe, I swear you will succumb to me
So baby come to me
