MIRAMAR, FL—During sexual intercourse Monday, Curtis Davie, 23, hoped that his attractive neighbor could hear the pleasured moans of his girlfriend through his apartment wall. "Don't get me wrong, things are going great with Amy," Davie said. "But it certainly never hurts to have a hot chick next door who secretly knows you're a sexual dynamo." To increase his chances of being heard, Davie is considering moving his bed to the wall between his apartment and the neighbor's, or at least closer to the shared air duct.
