Some idiot came up with an idea for the Vagina Hero, a game based on Guitar Hero. Deeky does a good job picking apart this little bit of misogyny. I just want to add: The game control is patterned after a VULVA, not a vagina. The vagina is that tube-like thing inside. The vulva describes the outer parts.
Here are just two reasons why adults might want to know the names of genitalia: No. 1, understanding different parts might help in bed. No. 2, when you're talking to a health-care professional, you want to be accurate.
OK, class dismissed.
