Looking for a song i heard on the radio

I think the lyrics are:

Do you like that, do you like that when I put it on you [boy]

Yea i like that, really like that when you put it on me [girl, christina milian??]

Here's a link to the wav file i got off the radio from flow935...
thanks for you help...

another one lyrics go like this:

feels so real when i think about you
words can't express the way i feel about you
and i can't go on with life, if i don't have you
baby boy, i just wanna be with you

ooooooooooo baby

TIA
