The birthing people who don't identify as women are female, or they couldn't be pregnant. Also, I can't reconcile opting out of womanhood with going on to do the most female thing imaginable, i.e., giving birth. What's manly or masculine or non-gendered about that? And for this we all get dehumanised and told we are birthing bodies, womb-havers, the nonsensical chestfeeders, etc etc.
I has my son on no real pain relief. It's nearly 30 years ago and I can't remember whether I had paracetamol, but I certainly didn't get an epidural. Gas and air wasn't much help. I was fortunate that it all went all right in the end. I remember that it was excruciating but fortunately I can't remember the actual sensation of the pain.
