I have a question about sick days/days off from playing. The other day my sub and I were talking about her denying me sex and would I just take it from her. The whole no means yes thing. Then the next night she got sick. Real sick, not just "sick" to test if I would take what I wanted. That brought up a whole new set of issues. If no means yes and you are both ok/into that, than how can my sub let me know that no really does mean no before play begins not in a safeword situation?
