Kiss
When you guys are together, stop, reach out and take his hand, then slowly - and gently - kiss him. That tends to break the ice beautifully. :>) or you could just say "I'm really tempted to kiss you" or say "I really want to kiss you." or if its your birthday or something say playfully,"So, do i get a birthday kiss or not?"
