People change too over the years in LTR. If each partner takes the attitude to always explore, be adventurous and care for one another, sex can be amazing and fulfilling for everyone.

Things get nuanced and learning how to excite and build each other's desire can be hard at times - especially if you're in the middle of a transition - but don't give up. At least that's my motto, something brought the couple together and learn to love changes because it's a new puzzle to solve.

Getting to a fulfilling LTR sex life is hard but well worth it IMHO.
