Does she like me when we kiss and feel eachother?

Hey, me and my girlfriend have been going out for a month and a half now and shes jist came back from down the country and the first night she was back I snuck over and we made out, we were feeling eachother and it was amazing... Shes way more experienced than I am and she had to help me with pokin her and stuff at the start but my question is that when i went to take her panties off she hadnt waxed and she was embarrased because she didnt but she said she was going to and that she always tells me how she wants me inside her but is this a sign she may be bluffing is actually to scared too yet? And when she gave me head she stopped a minute into it and said she probably shouldnt in case someone comes out and sees us ,.. But since then weve hooked up and done the same thing but she hasnt seemed to hint about goin further than touching and kissing. But most of the time we cant do to much because someone may see us or wonder where we are (were 17 btw). But she will rub me on my pants to turn me on but yea.. Any advice / help? Cheers
