Found This In My Space

I'd like to know what song the following lyrics came from, and who sang the song as well. I saw it as a headline for a My Space post.

The lyrics are:
"If I take you from behind
Push myself into your mind...."

I'd like to know the title of the song and who sang it.
Thanks alot, Ron theprettieststar
