I’ve had to learn what actual TMI is, since when I was a kid, pretty much anything more than, “I’m doing fine, how are you?” was construed as TMI. “Don’t tell anyone your business!” was the watchword I grew up with; alas, that path leads to shallowness.
But bodily fluids and what not? Yeah, I’m uncomfortable with that. I had a friend who’d tell me when she was taking her phone in with her to the WC, and I’d say, “Friend, I did not need to know that.” And she’d say, “Well, I didn’t want you to wonder if your heard a flushing noise.”
Oh. OK.
