First, you need to ask yourself what you want. Do I want to go on like this with your boss, or do I care? Or something. If you want to stay with your boss, pretend nothing happened and go to work the next day. Do what you should do as before. Don't feel that you are a head taller than others, or have other ideas. Don't let others see what you have or what happened when you meet your boss, as before. This is the stupidest behavior, because if you do this, you will not be far from leaving this company.
Of course, if you feel that you are put to sleep by your boss and still ignore you the next day, you are unwilling and want an explanation, then I suggest you give up this idea as soon as possible. Your boss told you that he just wanted to play with you and wouldn't take you seriously. If you don't want to, you can call him and ask for an explanation. If not, you can call the police and say he raped you. Of course, you can only leave this company and find another job.
In short, most girls talk big when they encounter this kind of thing. So what do you want to do? You have to figure out a way out and operate.
