basically don’t open up to anyone ever
But the idea that you can pull some sort of power play in a relationship by not giving the other person something which you don’t owe to them in the first place makes no sense. It would be like telling your partner that you’re going to punish them by not baking them chocolate chip cookies every day: sure, maybe they would like those cookies but in no way are you obligated to bake them cookies anyway, so they should probably be just fine getting along without it. The idea that you should feel as if the only way you can express that you’re angry or upset or unhappy in your relationship is by taking ownership over your body in a way that is so basic it should never have been a question is somewhat disgusting. If your partner has you so convinced that you owe them sex, no wonder you feel a little angry or vindictive towards them.
