Hey hey, welcome to the forums
With regards to your girl problem I think you just mention to her, as a passing comment about how shy/insecure you are. Speaking as a girl, that would absolutely NOT put me off you (although there is a chance that's only because I understand..) and I really think that it would help you. By explaining yourself, you've not got anything to lose because she'll eventually find out anyway. Just do it subtly and don't make a big deal out of it. It might be a problem if you don't really know her that well yet? Good luck, anyway!
