Is it normal i am facinated by a specific girl?

Hi. :) I am 18 yo girl and I am deeply fascinated by a specific girl. I have seen her commenting in this site and helping people in need.
Her name resembles most beautiful flowers and I am so much thankful to her that I am willing to eat her out if she agrees. (I am very good at it and I assure it will be very pleasant but only if she wants to.)
I am not in love with her. I just admire her so much.
is it normal I feel this way?
