" Consent matters after ten years just as much as after ten days, but it rarely looks the same after a decade as it did on the third date. Checks and balances that are crucial earlier on become unnecessary for both people now that they know each other better and can read each other’s cues. The forms consent takes will change, but the right to say no always must remain. If someone never wants to have sex, that is okay forever. For people who do decide to have sex, it is a choice each time, not a set of ossified obligations that are impossible to challenge or change. "
