Is he bored?

My boyfriend and I have been together for about a month and a half now. This is my first real relationship--well truthfully, my first boyfriend. But, everyone always says the first couple months is always fun! The honeymoon stage. But, I've known my boyfriend for a couple months before we decided to date, and he seems to be getting...bored. Maybe I'm just being over dramatic, but I feel like he maybe isn't interested. I've asked him about it many times, and he says, "No, I like you a lot." He was the first one to say, I love you. But, still. He seems to be always tired and all we do is either watch TV or sleep. His choice, not mine. So I have no idea how to be unboring or to get him to try new things with me. I have no idea what to do.
