I don't mean to offend anyone,(and I will edit if this is a problem) but I just don't believe minors should be filtered from knowing and appropriately using the proper terminology of their genitals. If it these terms aren't used in a negative, insulting, or innapropriate out of context manor I just don't see a reason for blocking them.
Edit: Thanks for the clarification Andrew, we were typing at the same time it seems. My point wasn't to subject anyones children to anything and if I need to edit I absolutely will. I went back to college to finish my degree in nursing so saying, writing, and typing these terms are kind of common place for me at the moment, I'n not trying to push any boundaries here.
