Just kiss her already. What's up with that? She's waiting for you to be confident and in control to kiss her first (when you're sober). Do it already. Confidence is a huge turn on for women. Wimping out is not. She has shown she likes you a lot. It's mutual. So what's to be scared of? What do you think she's going to do when you kiss her sober? Bite your tongue? Heh.
When you show that you know what you want and you're in control, trust me, she won't be able to keep her hands off you at every chance. You just need to get the ball rolling. If you're not initiating, why should she? It's all very well to want her to initiate, but I think most women like the guy to be the first to be bold if it's early days. It helps them feel confident to do the same back. Once you start it off, it should naturally progress to her initiating out of the blue too. That's when things really start to get fun.
