All vaginas are not created equal!

So I often undress and dress in front of my 4 year old son with the hopes that he will see me do this so one day he won't be overly grossed out. Anyways my son recently was at school and a girl wanted to change into her bathing suit but, she needed help doing so my son went over to help her but she did not need his help so she asked a teacher instead. So my son then followed her but, stood back to watch her undress. As soon as her bathing suit was on my son came over and whispered in my ear, "Mama, her vagina looks much much different than yours". I could not hold in my laughter but I did try so hard! I had to then let my son know that every vagina is different just like ever person is different. What a funny conversation to have with a four year old!
