Yes this very same thing happened to me when I was 25. Having gone to see a female doctor with concerns of rectal bleeding and sexual dysfunction issues, she told me to that she wanted to do a genital and rectal exam.
She told me to strip from the waist down and handed me a cloth drape as she left the room. This was to be my first ever recital exam and as I began to undress I very quickly started to develop an erection. I really didn’t want to be sitting on the exam table with a drape in full ‘tent’ situation when the dr came back in to the room, and so I decided it would be a better idea to wrap the entire drape around my waist like a towel ?. I figured if I wrapped it tightly enough it would help keep the erection down and therefore less obvious.
When the dr eventually came back in to the room, she looked at my drape solution and smiled. I nervously mumbled something about not knowing what to do with it, to which she replied, ‘don’t worry, it doesn’t really matter, it will be coming off anyway in a moment’
She immediately went to put on a pair of gloves, asking me if I had ever had a rectal exam before as she did so. When she came over to the table she told me that we’d be doing the genital exam first and so asked me to unwrap the drape and to lie down on my back. However as I was doing that I noticed she was applying lube to her gloved finger. As I lay there nervously watching she suddenly stopped and rather embarrassed, said ‘I don’t know why I did that, but seeing as I have lubed up let’s change the plah and do your rectal exam first, so if you can roll over on to your left side and bring your right knee up to your chest’.
It was a slightly strange moment, and I wonder if my unorthodox use of the drape didn’t throw her a little.....
