I started going to the dermatologist when I developed acne. The dermatologist I visited had everyone do a general skin cancer screening. Before they took you back to the exam room, you'd fill out a questionnaire to update your information. There were two questions related to the skin exam.
Are you comfortable getting completely undressed for the full body skin exam?
Would you like a gown during your skin exam?
I would always check the box that said I preferred to keep my underwear on and that I didn't need a gown. My mom and I would go back to the room, and the assistant would tell me to undress to my underwear. During the skin exam, the doctor would move my underwear around to get a better look, but I wore it throughout the exam.
When I was 16, my mom started letting me go into the room by myself at the doctor's while she stayed in the waiting room. That year as I was filling out the form, I stopped at the exam question. I wasn't sure why at the time, but the idea of getting naked in front of the doctor seemed kind of exciting.
I checked the box that said I was comfortable undressing and, without really thinking, that I didn't want a gown. This time when the assistant took me back, she told me to undress completely including my underwear. She didn't offer a gown before she left.
I stripped naked, sat on the exam table, and waited. I was beginning to regret my decision when the doctor came through the door. However, she conducted herself as if I was fully dressed. During the skin exam, she started with me seated. Then she had me lay down on my back. She inspected my groin, even lifting my penis. Then she had me stand up. While I was facing away from her, I started to get aroused. After she was finished, I sat back down.
It was next to impossible to hide my erection, but the doctor didn't say anything. She finished filling out my chart and left. I got dressed and went back out to meet my mom.
My MedFed started at the dermatologist, and I've enjoyed getting naked in front of her and other doctors since.
