On why you can't read Braille with your genitals
The key point is that the word "sensitive" is really too broad. So it can mean two different things: areas like the fingertips and the lips and the tongue not only can respond to tiny deflections, but they can precisely localize fine special features on objects or sense textures, the sort of thing you would need to read Braille.
Other parts of the body, like the cornea of the eye or the tip of the clitoris or the tip of the penis are very sensitive in the sense that they can detect very fine deflections of the skin, but they're not very discriminative. They lack the Merkel-type nerve ending. And, as a consequence, it will fail if you attempt to read Braille with your genitals.
