How do you get the shy & nerdy guy to kiss you?

Okay so I've been hanging out with a guy lately who I have known for about a year so far. Anyways Im starting to become attracted to him and wasn't necessarily attracted to him right away when we met. He is kind of nerdy and sometimes can be weird but once I got to hang out with him more he was actually really interesting to me and I was impressed on how intelligent he really was. He's an electrical engineering major and I think he tries to show off his smarts to me explaining circuits and what not because he likes me. But I think he's pretty shy when it comes to letting a girl know that he likes her. So now that its summer we've been hanging out even more like watching movies in his apartment or going out to dinner. He's been hinting somethings like wanting me to watch a movie with him by laying on the floor with pillows versus the couch or wanting me to walk on his back for a massage which is kind of weird but funny too. :) Anyways I feel like Im jumping back and forth in my head on if I should just go for it and kiss him or not. But he seems shy and I don't know how I can place myself around him to give him a hint that I would like to kiss him. Should I have my hand laid down closer to his or hit him with a pillow? :) Any thoughts?
