I had an interesting experience during a physical when I was 19. There was a fairly attractive African-American woman, probably in her mid to late 30's, who was examining me. She was doing the part where they examine your stomach and abdomen, both of which are very ticklish on me. No sooner than she touched me did my back fly off the table and I busted into stifled laughter, and I think I startled her a bit. She laughed and said, "Guess you're a little bit ticklish aren't you!" I nodded my head and told her I was very ticklish. She told me to just try to relax, and that it would just take a few seconds. She tried again with the same result. Then, no bulls**t, she says to me, "If you don't relax, I'm gonna have to stand here and tickle you all day! Don't be embarrassed to laugh, a lot of people get ticklish when I do this." So, I let her do her thing, laughed out loud for a few seconds, and it was over. I actually wouldn't have minded her tickling me all day, but I didn't want there to be evidence downstairs that I was enjoying it, if you know what I mean! 🙂
