It's not about getting old as such... I think it's more about the dynamics of the relationship.

As a relationship ages there can be feelings of resentment that have built up over a very long time.
IMO this is one of the main reasons women go off sex.

Billy Connolly: "Apparently, women need to feel loved to have sex, and men need to have sex to feel loved,
so the basic act of continuing the species requires a lie from one of you"
