Assuming you’ve recently had a shower, haven’t had sex, aren’t menstruating, aren’t just out of the gym, and generally are clean: is there a difference (in terms of cleanliness) between scratching your head, your underarm, or your pubic hair (just the top bit, not down below!)
My inclination is to say I would want to wash my hands after touching my bikini region and not my head, but if all of the above is true (recently showered, etc) is it really that different than scratching your underarm or your head?
