Then this kiss will also be for YOU to try to find that passion for her. It might be there. Actually, this kiss will tell you a whole lot of things....
Just be aware that it might tell you things you don't want to know -- but it MIGHT tell you new things that you need to learn about both of you.
I'm rooting for you.

P.S. DON'T FORGET the part about not doing it when she is already "doing something". She has to have her hands free and not be in the mindset of "doing something" else in that moment. Very important. The element of surprise should be there, but not to the extent that your actions suggest she should drop what she is already doing. That is why you need to make sure she wasn't doing something already.
