An older man I worked with (but not my supervsr.) asked to see my penis once, and I was very surprised by this because I thought of him like a father figure. He asked very politely and said he would understand if I refused, and that he'd tried to see once before in the men's room, but was interrupted. I told him I had to think about it. The next day, we stopped on the stairwell and I showed him. He didn't attempt to fondle, just acknowledged its largeness and thanked me. We never mentioned it afterwards (1-2 yrs), but I never looked at him the same way. I was nineteen.
