On my last physical exam I switch doctors and the new one was a handsome late 30'summer guy And very personable and charming. My clothes were on for the first part of the exam. Next the shirt came off and he examined and touched my upper body every where including my nipple. He then asked me to remove my pants, I wear boxers. And he then had me lie on my back, did some listening with a stethescope and touched just belbow the waist line in my pubice area ungloved. He then stretched and bent each leg and felt each leg all the way up to my groin coming super close to my dick and balls. Then he asked me to stand and drop my drawers. I was a tiny bit aroused but then he squeazed the length of my penis which chubbed me some more and by the time he was done with testicular exam and hernia check I went full hard. I tried to cover myself and apologized and he kept saying no worries happens all the time. He turned me around for the rectal exam saying he'll be quick and he was but it made me even harder. I was covering myself in embarrassment and he reassured me it was normal. He then felt my erections and testicles saying all was good and I could get dressed. He was so nice about it and kept reassuring me that it was normal.
