Saying "I Love You"???

So I have just entered my first actual relationship. My boyfriend and I are both in college and have been together about a month, so we're obviously still getting to know each other and are in the honeymoon stage, yadda yadda yadda... Anyways, I really REALLY like him! We have a ton of fun together, make each other laugh all the time, and are pretty damn physically compatible. The thing is that sometimes when we're cuddling or about to go to sleep I'm just so happy I feel this overwhelming urge to say SOMETHING. it's definitely not "I love you", because I know I don't actually feel that way quite yet, but I'm having a really hard time finding the right words that carry less weight than "I love you" but still express how much I enjoy being with him. Does anybody have any ideas? I really need something I can say as often as someone in love would say those three words whenever they're feeling moved, just with a little less commitment!
