You may benefit from reading my recent hub about my path to paganism. That said, no, you don't have to perform magick to be pagan. Paganism is a system of beliefs, no more, no less. Magick isn't a requirement. If you feel you identify with Paganism, then you're on the right track. If you don't feel an urge, or as you said compelled, to perform magick, that's completely natural. When I started on the path, I learned about spell casting and magick, but I didn't perform any for about 2 1/2 years, I felt I wasn't mature enough for lack of a better term. You have to be ready for it, and Mother Nature will tell you when you're ready. It's like falling in love, you'll just know.
In the mean time, as Dale said (Dale's awesome), enjoy yourself! Enjoy those connections to nature that you feel, and allow your bond with Nature and the Gods and Goddesses to grow. When you eventually do start down the path of magick and spells, your power will be stronger and more focused because you allowed the bond to solidify. Hope that made sense and I wish you the best on your journey!
