first of all, no physical affection is _necessary_ to show you like him. just talk to him, spend time with him, show your interest in all areas of his life... do you know if he likes you back, by the way? has he had gfs? if so, it's best to let him lead and learn from him. start w/ hi/bye hugs... at some point he'll probably hold your hand (don't freak out

). don't worry - just let it flow naturally and you'll be fine.
