Since my erection points up, I was thinking about how we measure along the top. If your erection points down, wouldn't it measure longer? I would think that to equate usable length of a penis that points up to a penis that points down is to measure the downward pointing penis along the bottom.
If I measure my flaccid penis along the top when it's pointing down, it's quite a bit longer than if I measure it pointing straight out.
