We're always looking for warmth and coziness. It's one of the finest feelings in life. Honestly, it's hard to concentrate on anything else when you catch a chill. All you want in the world is to be warm again.
It's especially true of toes. Sure, you can have some fun weaponizing your cold feet in bed with your sweetie, but beware, that game can be played by both parties. It's much better to just have warm, toasty feet.
