I have had that happen at the doctor's office, when in for a physical examination. The nurse just says "Start undressing, as I'm sitting on the exam table, still snug in button up flannel shirt with favorite warm ski pants. As she leave the room, all I take off are my shoes and socks, waiting for the doctor to come in. When the doctor(female) comes into the examination room she goes over my medical records with me, while I'm still clothed. As she prepares to do my physical exam, she asks the nurse to bring the gown for me. I have a lot of anxiety, realizing she will be feeling and groping my genitals and getting a rectal exam. I am sexually aroused, when in a lady like matter, tells me to strip off all my snug winter clothes, knowing I'm wearing several warm layers underneath. The nurse comes in with the gown, when the doctor says"Once he's naked and in the gown, start the preliminaries,let me know and we can complete the full physical. I'm sitting on the exam table in my snug winter clothes, blushing somewhat as the nurse says for me to step to the other side of the room, waiting for me to start stripping naked. Both the nurse and doctor stayed watching me slowly unbutton, unzip the snug winter snow pants. I really did n't want to fully undress, hoping I could keep the tights and sports briefs underneath on, but to no avail, since this will be a full body physical, everything comes off, no matter how long it takes to bare it all. Fortunately it was n't a busy day for them, so the doctor will be thorough with me. after,slowly and shyly getting out of snug warm winter attire,down to the tight white nylon sports brief, containing my now unavoidable full erection. Both her and the doctor said "Those undies have to come off too," "Don t' be be bashful,having an erection, it is a normal male reaction, when stripping for and during a male physical examination. I was blushing, slowly peeling the beautiful white briefs below my waist, Then the nurse reached under the rolled down waist band, gently freeing my excited penis from the clinging briefs. Then gave a few good pulls and the briefs were down to my ankles, as I did let out a boyish moan, with my erect penis standing upward, fully exposed, then in the gown, it looked like tent city under the gown, as the nurse did the basics, with me being naked. Now the doctor stepped in and commenced the major part of my physical including the genital and rectal examinations, totally naked, the gown was taken off during the physical. I was still hard, putting on the change of underwear and baggy clothes. I got a clean bill of health for another year, but it was a long afternoon, especially getting all my warm and snug winter outfit off, under their watchful medical eyes.
