Tight scrotum during physical

As I posted earlier in this thread, my penis and scrotum shrink and shrivel terribly whenever I'm examined. Mostly due to anxiety, nervousness, and/ or embarrassment, but the coldness of most exam rooms don't help.

I have exactly the same. The first time I noticed this was during a military medical examination. I was examined by a woman behind a screen. She told me to take off my panties. I was embarrassed and looked down. I saw my scrotum and penis was shrunken. The main reason for this was shame. Seeing that, I was even more embarrassed.
