I DID ejaculate once, during an exam. It was outside the US.... I was in a small clinic. I managed to have the staff nurse attending to me, as i needed to be catheterized and gently dilated. After a very long wait when i was hospitalzied overnight, she finally came in to examine me. As she slid the catheter gently in and out of my opening (to dilate it), it came too fast and i could not control it... and no erection, either, as it went way too quickly. It was the scenario, and the exposure, and the gentle in and out. I asked her to stop (as i was at the amazing edge), she did, and it all just bubbled out... i was biting my lip, trying not to moan... however, she was a trooper and rested her hand on my thigh and just observed. There was no 'shoot'. I finally calmed down... i was embarrassed, but loved it. I apologized to her , and she smiled and said not to worry, as that it would happen on occasion.... and she didnt make a big deal about it. She even got tissues and warmed washcloths and cleaned me up. I saw her later, and apologized again for 'la emision', and she smiled and told me it wasnt a worry, as it would happen on occasion with male urological patients. I managed to play it up, and discussed it at length, as i found it so clinically humiliating, but loved it.
