Why wait for her to take the lead? Why is it important? When my gf comes over I can't keep my hands off her, I don't even think about these things. To me it doesn't really matter at the end of the day who initiates what as long as we both have a good time.
I think the tangent you are going off at is that she doesn't show affection to you (At least not as much as you want) Well, just talk to her about these things. Say it out laud. "I'm not happy with you not giving me affection". Then she'll either change or break up with you, either way, either one is the outcome you're looking for.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
