In 4.11 (TOW Phoebes Uterus), what were the 7 erogenous zones Monica taught Chandler about?
The writers only established that Monica talked about seven zones; they did not establish any information about what those zones were. Even in planning this storyline, we can’t be sure the writers bothered decide what the 7 zones were. They might have used the number 7 because they believed that number was accurate, or they might have chosen 7 just to make everyone wonder. But I’m sure some people would say there are more than 7. Since the purpose of my site is to collect established information about the show rather than speculate on things that were not revealed, I am not going to attempt to speculate about what the 7 areas were or how many there really are.
