Men (and some of them deeply hate it when I say this) can go indefinitely on masturbation alone with no real problem. Your partner may prefer sex, and if he doesn’t love you enough to work through what big-picture problems are causing your aversion to sex he might leave (in which case good riddance), but it’s only ever a want, not a need. If you’re not feeling it because the kitchen’s a mess or you’re worried about bills or you feel unsexy or the kids are still awake, he can wait. He learned at a very young age how to take care of himself; he’ll be fine. And you don’t have to have anything to do with that either if you’re not feeling it.
But seriously, who am I kidding? I know nothing, and neither do you. If 100 days of meditation has taught me one thing, it’s that I have a lot to learn. We’re all just comparing notes. As the Zen proverb says: To understand nothing takes time. Once you realize that, you can experience, enjoy and learn from the journey a little more deeply.
