I quickly answered socks of course.
They both laughed pretty hard and said it was unanimous. Every guy said socks and every girl said underwear. No exceptions.
I have no idea what this means in the grand scheme of things, but I thought it was interesting.
A friend of my son was in the “tip of the spear” when the Marines first went into Iraq in 2003 or 2004. He said THE MOST IMPORTANT thing to get in care packages was new or clean socks. They didn’t get to shower for several weeks, and hiked many miles in hot desert sand. There was some rule about the Marines had to have regulation socks that were the olive green color (even though they did not show at all with their uniforms and boots). We eventually got to where we would just dye athletic socks with Rit dye, and eventually the NCOs relented to allow them in.
If you must know .... a typical and healthy cervix discharges mucus pretty regularly. Not much, but it does. Think of a self-cleaning oven. Add to that the labia is a moist area with little ventilation. Smells happen. Doesn't mean one is dirty. It just means that you need to bathe more often.
Penises don't do that so, of course, the guys wouldn't see the need.
