Is she giving me hints?

So me and this girl have been going out for about 2 month now we haven't done anything yet i haven't even kissed her because im shy she told me she dont care it will happen when it happens. I know she wants me to kiss her because when people are kissing on tv Ill say i need to take notes and she'll say I know and laugh. I want to know if she is hinting that she wants sex. My nephew grabbed her boob in the car hes young and she said wow thats more than your uncle does. I we were watching tv and is said something about the big bang I asked her when it was and she said whenever I grew a set. people were having sex on tv and I said atleast there getting some and she said I know what am i going to have to wait 2 years. Is this her way of hinting to me ? Thanks
