> Because even with hygiene products, people buy them before they need them and stock up.

One would think so, but in my experience this is not the case on average. Of the half-dozen long term relationships I've had, only 1 partner was ever prepared for the monthly inevitable. For everyone else it was always treated as a surprise. Suggesting to my current partner that she stock up on the products she just used was dismissed with an "oh I don't need that stuff for weeks".

The trope of guys not wanting to go get tampons, or uncomfortably navigating the feminine hygiene isle, did not just appear out of nowhere.
