Vaginal speculum up the bum

"Best to get the proper tool for the job " : )

Depends on who gets it. I couldn't take it without much damage, but then some can take to man-size hands so i think is pretty possible.

Be careful however, it's quite decent size you are talking about, and if you cannot fist her even with one fist, just forget the whole thing.

I've performed rectal speculum exams a number of times. The correct size and type of speculum is crucial for patient comfort and the key to her enjoyment of the procedure. I strongly recommend using a Pratt Rectal Speculum which you can usually find available on eBay. Look for the simple two-blade version with the thumbscrew. It is nicely rounded at the tip and along the sides of the blades for easy insertion and anal dilation. In my opinion it allows allows for better visualization of her rectum than those three-blade Mathieu type.
