When people have sex, they generally enjoy a private, intimate moment with their partner. That’s usually when the cat likes to jump on the bed or simply stand to one side and stare. Having another pair of yes watch you can feel creepy and spoil the mood, so you need to plan for removing the cat distractions during sex ahead of time.
First, set clear boundaries that your bed is not the cat’s territory. Second, realize that your cat is not the boss and you have control over the situation. Third, realize that no matter how much you try, your cat is your boss and you have to submit to the will of your cat anyway.
