I don't think there's any such thing as sexual boredom. When people complain that they're bored, it’s usually because uncomfortable feelings are coming up. The brain does this nifty trick of bypassing uncomfortable feelings and going straight to “boredom.” We tell ourselves we're bored so we don’t have to feel.
Boredom isn’t pleasant, but it’s better than the alternative. When couples come to me complaining of sexual boredom, my antenna goes up. I know that boredom in the bedroom can be about a variety of things, but it’s generally not what they think.
“Sexual boredom” has become a catchall term for what ails those who have lost interest in sex with their regular partner. It can mask unresolved conflict, power struggles, laundry lists of resentments, physical aftereffects from childbirth, depression, complacency, unsatisfactory birth control, feeling unappreciated, fear of rejection, lack of confidence, or other such vulnerabilities. It is the result of stagnant energy. Sexual energy is part of life energy, and when it doesn’t move, listlessness sets in.
