If a guy brushes his whole body against yours, is it a sign of attraction?

How about letting you rest your hand on his arm for a long touch without moving away?

Thank you everyone for you input. Last night I decided to take some action and asked a buddy of his if he was single so I could go after him without reservations. Well, it turns out he is in a long-term relationship. He wasn't shy, he was interested but hesitant.
