I Am Confused About My Relationship

So, I love my bf, but this is my first long relationship really. I am getting bored with him, because we are diffrent in a lot of ways. I find when I am listening to him I ignore what he is saying, because it's always about computers. I'm a artist and writer, so I am not super interested in computers. He also talks a lot like a math teacher, monotone. I love him, but I guess I want him to change. I have a lot of great things I could say about him, but I am confused about life. I want to experience what kinds of relationships are out there and if I am truly strait or if monogamy is for me. Yet I have a great bf and I don't want to ruin that. Anyone feel the same?
