Have a talk or natural consequences are enough

I dont know how to say this. So I'm just going to say it. My ex called me to tell me he's in the ER with our almost 16 year old son because for whatever reason, I'm assuming masturbation, decided to put a shot glass up his butt. It didn't break thank God but my custody time is tomorrow. My ex is saying he's not having this conversation. He thinks natural consequences handled that. I feel like we do need to talk about it. But at the same time I think he would rather forget this happened
