My man and I have been together for a bit, and I'm afraid that he may think things may be beginning to get repetitive. I need some ideas for new ways to express my feelings to him, and new things we can do together. I just want to keep this relationship alive and kicking. Anyone have any creative ideas? "I love you" doesn't seem to be enough... I need a better way to express it. And some activites/etc would be useful, too.

(If it helps to know, we are sexually active, so suggestions of a sexual nature will also be helpful)
