What does it mean that my crush likes to hand feed me and share his cup?

My crush likes to feed me. He's fed me icee from his spoon, cake off his fork, asked me to try his drink and yesterday offered me a chocolate by putting it in my mouth when he could have just pushed the box toward me. We flirt like crazy, but I'm wondering if this is hinting for something specific, or just increasing tension between us. We haven't kissed or anything, just touchy feely stuff, hugs, etc.
