In my own opinion, I think God has different ways of talking to us about issues like this. If the two people are not yet joined, this might be a pointer that there are dangers ahead but if it can be amicably resolved between the two partners, I see it also as a pointer that something good is going to come out of the relationship.

But in a case where the two people are already joined, as in married. Then whoever that is feeling boring should meet his partner and let him know the areas she is bored, then two of them can join hands together to work it out. Never allow the experience to drag to the extent of giving your spouse gap for a long time, for this spoils relationship.

Always keep the communication line OPEN.
