The intimacy coordinator question — how to bring it up professionally

I've been on 3 sets now where there were intimate scenes and no intimacy coordinator. Twice I just dealt with it (uncomfortable but not unsafe). Once I asked if there would be one and the director got defensive. Here's what I've learned works: ask during the booking stage, not on set day. Frame it as 'for everyone's comfort and protection.' If they react badly to the ask, that tells you everything you need to know about how the set will be run.
