I usually wear no line nylon men's bikinis which solicits an enquiring look most times. Just the insertion is always nice and I give a little groan that could be taken for a number of things. Seems to give me a few more seconds. I love the cancer check on the scrotum exam, sometimes wondering if thos extra circlings are being enjoyed.
I once did a volunteer test in which I swallowed a small lighted at both ends circular camera . It was reminiscent of Fantastic Voyage. I was able to watch on a viewing screen the entire trip through my upper G.I. system, then onward through the lower. I had been given a relaxation med that caused me to get excited as I dreamt of Rachel or the doctors in the submersible travelling through my system. The doctah was a female Oriental, very professional, but with a little amusement in her well guarded eyes. She looked at my eyes as she adjusted my gown which had slipped and in doing so, passed her hand alongside my "equipment". My eyes gazed upward, nostrils flared, ass clenched, and breath loudly into. Variations of this happened several more times. I didn't make any comment, but would have if another time occured, because each time it seemed her adjustments were a bit stronger. Sorry I am. Probably you too. It made for some good solo times at home !!!
