Health problems, side-effects from medication, or relationship problems can block your sex drive.
Generally as long as you’re…well, alive, you should have a healthy sex drive!
But it can be blocked by other emotional problems if they’re serious enough – fear, for example, or resentment. If one of you is experiencing a lot of resentment, it can be a real kill-joy! If your sex drive isn’t what it should be and you’re in perfect health, ask yourself if you’re really happy in your relationship, and you may well have the answer.
