My GF doesn't know what I'm into

"I've always been looking at you from afar. I began to like you from the moment we first met, and I can't keep my feelings hidden anymore. Please come to the big cherry tree after class. I want to tell you how I feel." My new girlfriend is so cute and sweet. I can't believe such a nice girl likes me so much. But... would she still want to be with me if she knew what I'm into?
