[perfect stranger]

I probably know too much already.

I hesitate to suggest this unless you have safe search filtering turned on, but if you google Speculum and then open the images page, you'll see the device.

If you don't have the google safe search filtering turned on and you run the search, you'll soon find out why I hesitate to make the suggestion.

If you are under the age of 18, please do not do a google search for speculum.
