Who finds having to give a urine sample extremely embarrassing?

I don't find it embarrassing usually as whenever I have to provide a sample, I produce it at home at take it to the appointment with me. When it has been embarrassing is, as others have said, when I've been watched or as a 5 or 6 year old child when the doctor wanted a "clean catch" sample instantly & insisted on retracting my foreskin, cleaning my glans and then holding the containers - he wanted the sample split in 3 parts. At the point when I didn't stop the flow instantly after the 1st portion, he tightly pinched my penis & didn't let go until he'd got the 3 portions 😢😡. Why he didn't instruct mum to supervise me I don't know, but think it was a "control / power" element for him.

I don’t find it embarrassing itself, but I always hope they have somewhere for me to leave it or something, because I hate having to come out of the bathroom with it and hand it to them. I don’t know why but that is the only part I find awkward. Just the handing it to them.

At the lab I go to, they have a small door on the wall in the bathroom where you leave your sample. When you open it up, you see there is a door on the other side. It's a pass thru the wall with a door on each side.
