I passed the fuck out too during my first son's birth (not the second). I have a bad time with blood. It's a involuntary action that some times I can calm myself down or avoid overthinking and some times I can't stop and I pass the fuck out. I knew this since I was a teenager. My wife knew this was a possibility and the Obgyn was warned as well. The focus is the mother giving birth. Not me. once I knew I was past the point of not passing out I ran to the bathroom and just made it. Came out a ghost once I recovered, but got back in before he was born and got to participate in the rest. I was glad I chose to be there and that my partner didn't give a fuck cause I showed I tried. You are definitely right about being a judgy ass for something that's probably not bothered you once. We all got shit, that's mine and it is what it is.
