How do you let him know you want to be more than just friends? Use his sense of touch to ignite his passion.
Gently stroke his hand or arm, touch a freckle or scar (they all have them) as you ask him about it tenderly. As things progress, stroke his hair, hold his hand, and let your hands do the talking.
Remember, you don't have to wait for him to make the first move. He's probably as nervous as you are. So lean in and pucker your lip, but don't come on too strong. Although it's OK to initiate the relationship nowadays, he still needs to feel he's the man!
