BS”D
The story is from Rashi Avoda Zara Daf Yud Ches. Other Rishonim (IIRC) disagree with that being the issue of why that Tanna had to leave, and doubt Rashi’s story (saying that if she was actually M’zane, she would not have been note as she was in the Gemorah.) (Also (personally) noting that the Tanna in question had a similar situation (and failed) brought down at the end of Mesechta Keddushin, so her Z’nus would have not proved anything anyway regarding men vs. women & Da’atan Kalos).
However, IF THE STORY IS TRUE, you have to know who you are dealing with. Tannaim are not people like us, they are people. We are like Donkeys (and not R’Pinchas Ben Yair’s donkey either, and probably not even Billam’s Donkey)(quote). Respect to the point of awe is an absolute must.
