Digital Rectal Examination is designed for training in male and female rectal palpation.
I was sent a link to a company in Japan that makes, among other things, anatomically correct dummies for use in medical schools. Above is a picture of one of their products.
As serendipity would have it, I happened to be reading that day an article about China's biggest sex toy manufacturer who also runs a chain of retail stores and is about to begin a franchising operation. I sent his company an email about the Japanese site thinking they might be interested in stocking this item, though buyers may not be limited to aspiring proctologists.
