It is. You can always cut something off later, but you can’t just put it back once it’s gone.

Based on this conversation, I actually asked him:

Me: Hey man, so feel free not to answer this if it’s too personal, but I was having a debate about circumcision and another parent challenged me saying I’d made the wrong decision. So yes/no/I don’t want to talk about it cuz that’s weird, do you regret my decision?

Son: I don’t, and none of my partners have, either. I only get thumbs up and compliments. I hope that wasn’t too personal.

Me: Not at all. Thank you for giving me your and your partners’ review!

So yeah, no regrets.
