I noticed the questions about what the cervix feels like, etc, and did a bit of research. I havent been able to find an acceptable link with a pic of anatomy on it for the "where" question, but I did find these.
This first link is a photo of a real cervix, and not for those who are faint of heart! But, if you dont mind the very graphic, it will give you an idea of what a cervix looks like. It is a closeup shot, so it is not actual size, but you will get the idea http://www-medlib.med.utah.edu/WebPa...ML/FEM002.html
This second link is to a network of sites (OK'd by the mod) that has a great deal of information about the female body, hormones, etc. http://www.e-gynecologic.com/#Anatomy
It is probably a bit more suited to those who dont know much about how their body works, but I found it pretty interesting and detailed. We ought to add this second link to the "Info for teens" thread!
