" I'll also wear them if I'm wearing loose fitting shorts and think someone may call the cops if they accidentally catch a glimpse of Long John Silver."

Well I wear baggy shorts almost all the year round, in the house or out, and always when indoors as Mrs Steve and I suffer from severe indoor temperature incompatibility, and she wins. Going commando in such circumstances carries the severe risk of inadvertently providing flashes of the meat and two veg up one leg of the shorts unless I permanently avoid the alpha male legs-akimbo thing by sitting primly with my legs together, little girl fashion, which I don't. A number of photos of me have had to be deleted for this reason (they are known as "crotch shots"). Actually, wearing boxer shorts alleviates this risk only slightly, but it's a start. I'd rather risk a glimpse of the real me than risk the same wearing Y-fronts, which makes it look like you've stuffed a well-filled doggie poo bag up one side of your shorts. And women think they have bra difficulties. Tsk.
