Incestous CSA, take about personal freedoms some people might not like.
But I think its a bit unreasonable to demand that everyone, cw or keep their relationships secret. Treat this like any other sexual minority. And your asks about it like any other trigger. Ask your friends not to bring it up around you sure. I'm not out here trying to erase blues clues from existance. If you wouldn't ask another sexual minority to cw all their sfw posts about it. Think about why you feel its fine in this case
