I just dropped a pair of scissors on my crotch.
They don’t teach you how not to do that in elementary school… though I understand it should be naturally assumed, given the whole human propensity for self-preservation and species propagation instincts.
Somewhat interesting that the same biological reasoning that explains why sex feels so good is the same reasoning to keep shearing objects safely in-hand as opposed to dangerously in-crotch.
Still hurts.
