Hi ET27....No, it doesn't happen to all couples...Things may slow down, but you must keep that part of yourself alive that first found the happiness of making love...Thinking back when I was younger I was not as hungry for sexual gratification as I was as I aged....Funny as it may seem, I believe the books are wrong in this respect...They say we are in the height of our passion in our 20's, whereas I found the late 30's and 40's were great and into the 50's it was like being a cat on a hot tin roof....
Unfortunately, the sexual wants of a man and a woman are not the same...I believe a lot of what you feel is felt by many women, including myself of years ago...But, my husband could turn me on...I may have fought him mentally, but I did give him time and he proceeded to make a liar out of me...
If you love him and plan on marrying him, then this part of you must remain alive...You see once a woman forgets this special part of herself that is alive, she may find that she enjoys it....Thus, marriages get into trouble and unfortunately there are many other women both willing and able to step in to keep him happy....
As far as keeping it alive, we have been married over 53 years...I have no idea where that time has gone, but it is gone...This morning I awoke to my husband naked in bed beside me...He darn near froze me to death as he had been mailing and gone out with the puppies...Needless to say, he wanted me...and he got his wish...I find that a woman can be awaken, but this is the part of you that must remain alive....As you age you will find that keeping this part of you alive also gives life to your husband/lover....You see at that time in life they need it....
I often wonder why it is that so many women struggle with what you are talking about...As for me, he was the only guy I ever dated that stood me up...Maybe that is why I live in the land of Oz....I still adore him...I send you my best wishes...Take care...
