Set AITA for refusing a kissing scene when there was no intimacy coordinator?

I was booked for a micro drama where the script included a kissing scene. When I got to set, I asked about the intimacy coordinator. The AD looked at me like I was speaking another language. Turns out there was no IC. The director said "we'll just block it in the moment, it'll be natural." I said I wasn't comfortable doing the scene without an IC or at least a pre-agreed choreography. The director got annoyed and said "it's just a kiss, this isn't HBO." They ended up rewriting the scene to cut the kiss. But the director was cold to me the rest of the shoot and I could tell the other actors thought I was being dramatic. For context: I'm a woman and the scene partner was someone I'd never met before that morning. Was I being unreasonable? It genuinely felt like a safety issue to me but everyone else seemed to think I was overreacting.
