Are you or do you know anyone who’s “pee shy”?

I had a friend ages ago, she’d make me come into the bathroom with her and talk a lot while in there, though if it was a single stall, I had to face the other way. She didn’t want anyone to hear her pee…she admittedly would let it dribble out so as not to make noise.
(she also had smelly feet, but that was another story)

Is that “pee shy”? Is that the same as not being able to pee in a public bathroom? Is it hard for some people to do that? why? If you gotta go, you gotta go right?
