I'm not sure why you'd want a girl to just strip and not sleep with you. I've had girls strip for me. Usually it's when we're alone, in a room, there's music and I say "I like to watch you dance. It's sexy." That's usually enough to get them dancing. Then "Take off your xyz."
That's about it. If she's down to sleep with you, and she likes dancing, most women really get off on stripping for their guy.
