I have an average sized penis but it can shrink very small when I'm nervous, like at the doctor. I had an appointment today with a urologist and she happened to be pretty young and cute, as I would like to think I am.
When I laid down, shorts removed and the exam began, my penis was literally the size of an acorn, and shrunk within my foreskin even though I am circumcised. I was concerned she might think I have a micropenis!
Once she proceeded to examing my actual penis, luckily it came out of hiding to my normal flaccid size of about 4 inches and she was able to check it in a normal state.
After several minutes spent attending to other aspects like the prostate check, we seemed to be wrapping up. During that time, my penis shrunk back to its hiding state (why do they keep the office so cold?! lol). My scrotum also pulled up super tight.
I don't know if it was just me, but the urologist seemed interested by the case of the reappearing and disappearing penis. I thought we were wrapping up, but she then spent several more minutes examining my shriveled penis. I wasn't sure if the shriveled state could somehow be medically relevant to my issue, and she was checking if that was the case. The thought did cross my mind that because the first time she began feeling my penis, it began to grow (not getting erect though), she wanted to see if that would be the case again out of interest or even entertainment. She did seem to take her time before having me get dressed, but my penis remained in hiding.
I wonder if seeing penises shrink and reappear like that is a common thing for urologists, and if it's medically interesting to them and even sometimes personally interesting.
