I think you should completely be yourself. If you spend so much time together he must be sending some kind of signals that he really cares for you. Maybe he is nervous to say anything to you, in fear that you won't feel the same way. I think you should go ahead and be up front with him. You say he doesn't play games but this is kind of a game if you don't say how you feel. You aren't being honest, to protect yourself. What do you have to lose? The friendship? You never know, if he doesn't feel the same you may feel like a dork for while but it may strenthen the friendship. Or maybe this could be the greatest thing that ever happens to you. Do something today. Think what a wonderful summer you could have together, physically and emotionally. Go for it!!! This is just my opinion and it DOES NOT make a survey. Good luck and have fun.
