I don't get it!!

My husband and I have been together for almost 5 years now married for 1.5. In the beginning our sex life used to be crazy but recently I have been finding that I am just no longer sexually attracted to him and idk I don't get turned on. He's a little awkward when it comes to foreplay so that doesn't help but I feel terrible. We've talked about it and hoped to make changes but nothing has happened :/ I feel like as a result of this I've been thinking way to muh about other men :(
