Setting aside the legitimate concern over sensitivity of the general area, did you actually try for yourself? My research study of 1 is exactly as the other studies show: my stretched flaccid self approximates me in my turgid, nail-hammering glory. I think I'd find it more imaginary (or a real doozy of a medical condition) if your unit *doesn't* stretch given it is comprised of elastic skin and spongiosum and other stretchy goodness.

Though I did get to learn this morning that I'm roughly "porn star level" by at least one person's definition so my ego is swelling nicely.
