E. Jean Carroll, Elle magazine columnist: I want to be perfectly clear here: Any question a guy asks you has to do with sex. "Do you want to come up? ... Have a drink?" He's asking you to take off your clothes and get into bed.
Ceri Marsh, etiquette columnist: This is dating subtext for, "Is tonight the night?" If you're only interested in another drink, stay at the bar.
Kim Izzo, etiquette columnist: With a one night stand, you can't have expectations.
Harriette Cole, syndicated columnist: If it's night time and you're going up to his place, there's a possibility—no, a probability—that he wants to have sex. If you're not sure if you want to, don't go. Kiss him at the door and say, "Bye."
