Boring sex

My boyfriend and I just started having sex about a month ago. Now keep in mind I'm only 18, so this is my first real relationship that involved actually having sex. But my boyfriend is constantly wanting to do the same thing in the bedroom. Turn off the light, lay on the bed, same position. Every. Time. And I don't know how to tell him that I need spice. He's just not that type of guy. I love him but the sex isn't satisfying. Help!
