Your question is a little creepy. My straight up answer is 'back off.' Either she's too young to be going out to a movie or skating or bowling ... or you are expecting her to become intimate with you, which is way out of line.
This is a list to give clues about whether or not a girl likes a guy. In case you haven't figured it out yet, I'm here to tell you that a girl liking a guy means she's interested in spending time with him to get to know him. It doesn't mean she wants to instantly make out with him, sleep with him or let him be anyway 'intimate.'
Forget about her 'not understanding what to do' because she's scared and 'it is happening to her for the first time.' That's not the problem. I think you're the one who doesn't understand. So let me make it clear:
If she's not ready to go out with you at all, then back off. Maybe when she's older, she might think you seem like a good guy to date. Or maybe she won't, so don't hold your breath. Just find another girl to ask out.
But if you're trying to get her to kiss you or let you grope her or whatever, and she's obviously not consenting to your advances, then you should certainly back off.
Just because you want a girl to do something, doesn't mean it is going to happen. If you don't learn to respect that a girl has a right to say 'no' for any reason at all, you'll be facing sexual assault charges before you're much older.
So, in answer to your question, you should 'conclude' that you're making a big mistake and need to change your attitude. This is real life, man, not some teenage movie where guys get to grope girls and go home when the credits roll. Treat women with respect, and you'll have a happy life because sooner or later you'll find one who wants to get intimate. But you have to wait to find the right girl. This girl is not the one.
