What is the name of this song?!!?

Here are a couple of phrases: 'tonight's the night! Everything's gonna be all right' and 'slip out of that French, silk gown'(something like that) and 'hush my virgin child' and 'let me pour you a nice long drink'. the meaning is about a guy basically telling his girlfriend he thinks they're ready for sex. It sounded like it should be jazz and from the 80's or 90's. It sounded very romantic and if anyone could tell me the name of it, that'd be great! Thanks
