Many couples who have been together for a long time have difficulties in maintaining a healthy sex life. The reasons are many and varied, of course, and can include:-
* changes in body image and sexual confidence due to pregnancy and childbirth
* lack of energy due to the demands of work and parenting
* the challenges of keeping sexual intimacy fresh and exciting with the same person over time
* dissatisfaction in other areas of the relationship that mean one (or both) no longer feel like being intimate, sexually or otherwise.
