What is the flying bug?

I took an intro flight today to see if I actually liked flying. I was nervous hopping into the cockpit. When we take off and climb, my nervousness goes away. The CFI eventually lets me have the controls. When we were straight and level, everything felt normal and relaxing, no motion sickness, no nervousness. Honestly to me, it felt very similar to being a passenger in an airliner. For me it was enough for me to confirm that I do want to be a pilot. But I feel like I didn’t get that “freedom of flight”, excitement or love of flight that I hear other people talk about. I genuinely did enjoy it and would like to do it more often. I will say that on the drive back home, I was smiling the whole time like I had just gotten laid.
