I went to dinner with friends -- 3 guys and another woman -- at a wonderful favorite hole in the wall in San Francisco when the conversation turned to female anatomy in a factual way since all 3 guys were gay. several times someone tried to move the conversation off to another topic but it never took.

at one point one of the guys shared a story of how he learned about female anatomy. I forgot most of the details because my short term memory was wiped from the laughter by the time he got to the end of his story. somehow a real woman was available and "we were paraded by her as she lay on her back with her cervix and vagina visible through the use of ... oh, what do you call those things ... salad scissors?"
