I have been going to the same doctor for many years. But the last couple of physicals I have gotten completely hard while he is giving me the hernia exam. This last time I was half hard as he palpitated my stomach and continued to ask how I felt. He mentioned the next part of the physical would be the hernia test and testicular exam. For some reason I have recently eroticized this part of the exam.
He is a straight doctor and very professional. Last year he saw my half hard dick and said 'it is good to see that something is working well. This time my erection was so fast and obviously erect he just ignored it and did the tests without a comment. It was interesting to feel my erection throbbing while he scanned my testicle with his fingertips. Most interestingly he has never given me a testicular exam before. He mentioned each year prior that it was something I needed to do for myself.
One of my favorite moments is the feelings and getting an instantaneous erection. The spontaneous erection is very pleasurable. I find the feeling of getting an erection in anticipation of flirtation, thinking about being fondled or when I cannot completely hide the fact the I am getting wood in my trousers such an incredible feeling.
That is how the exam ended. I hope each year he gets a little more curious to make sure everything is fine with further examination. There is nothing more exciting that the idea of being touched, examined and masturbated by one who is in more control.
