Exactly. No pain on my bike, which is a hybrid with a roadie saddle. Yes, folding metal "church chairs" are a killer now, as is the race-seat in my race car (sheet aluminum with a cloth cover).

It's as if someone slide my spine down about an inch while I was sleeping, so that my tailbone is now too long. So weird.

Maybe that bone area needs to toughen up, much like the sit-bones do when we start cycling. I had sore sit-bones for a week, then it magically went away. Maybe my tailbone area, having been WELL padded for many years, kind of got soft, and just needs to HTFU again. I would guess skinny people are already equipped, much like a cyclist who never gets off his bike for too long never has to re-do his sit-bones...
