Hi,
Your objective is to get good result and you find her teaching good. I would say you have found the right tutor. As for the attraction towards her, I think if you treat her like a sister, you would't have those fantasy. You would rather be proud to have such a clever and beauty sister instead. Therefore it's all in your mind.
And next time, you will find more of such ladies around you. By knowing how to respect them as a sister, you are growing to be a gentleman. All ladies like gentleman instead of a guy drooling horribly at a woman.
You are still young, and a lot of things for you to learn. This is just one of them. It is good that you want to know what you should do. Keep it up.
