I can't explain this feeling....

My husband and I have been married for almost 4 years...we have always had a great loving relationship...with an occasional argument here and there. But for the past few weeks...we just can't get enough of eachother, and the feeling that I get when I look at him is even stronger than when we first started dating. We have went from having sex to 1 or 2 times a week to almost every day. Gosh...I just don't want it to end. I just get so lost when we are with eachother...words simply can not explain how much i love him. I just want to cry im so happy. Anyone else ever went through this?
