You need to decide what you're comfortable with sexually and set firm boundaries.
Most men will continue to pursue sexual escalation until you firmly indicate you're unwilling to go any further. This was probably not an issue with JW men, but that's the way the real world works. If you're unprepared for this reality or if you freeze up and don't set limits, men are likely to continue to escalate the encounter.
Does that mean they view you as a sexual object? Not necessarily. Some women are very openly sexual and have no hang ups with having sex on the first date. If that's the case, you won't find many men who'll refused to oblige if she's willing. It's up to you to indicate what you are and aren't comfortable with.
Best of luck to you.
