Asking your wife for anal while her vagina is actively being torn apart from the inside is definitely crazy.

Kind of, but I hate seeing stuff like this:

And while you’ll be hard-pressed to find many experts who support unassisted births—as in, at home, without the presence of a physician or midwife—the core of Shanley’s philosophy stems from a concept that has existed for millennia but has been diminished in the past century: The majority of births are “normal” and don’t require medical intervention.

I'm glad the author prefaces that saying that experts don't support unassisted births. Of course people have been having unassisted births for millennia with the majority being normal. But we used to have much higher infant mortality rates compared to what modern people would deem acceptable.

Personally, I'd have a dead baby and probably would be a widower if my wife hadn't given birth in a hospital.

Except the part about the husband asking for sex when she was in active labor. That's pretty bonkers.

The theory is there and it seems to make sense biomechanically, now we need more studies on women doing this during birth and see if it results in less labour, pain and/or interventions.

Not like that. Never like that.
