I feel the same way, but thats practically with eveyrthing in life. Sex when your young seems so precious because u barely had it. Ofcourse ur gonna treausure something new. Compare it to a car, lets say u get a brand new car, and ur loving it. In a matter of a few months it's just another car. U can have the best sex, but if u have it all the time, specially with one person, it's going to get boring mighty quick.
