If you like him, then you like him. That's really all there is to it. Labels are useful for describing yourself to other people, but they're pretty useless for understanding yourself.
If you don't think you want to have sex with him, then don't set out to have sex with him. If you want to make out with him, and he feels the same way, then give it a shot. If it feels weird, like making out with your brother, then stop. If it turns out you actually get turned on, and you want to do more, there's no harm in doing more. Basically, there's no required progression for physical relationships...you can do whatever the hell you want and label it whatever the hell you want and it's nobody's business but yours and your friend's.
