Theatre for some of the fiercest battles ever experienced by mankind. No doubt that countless relationships, even marriages, have been sacrified as casualties of the war over who sleeps in the spot created during a (hopefully good) roll in the hay. I wouldn’t be at all surprised to find lawyers hashing this out as part of prenuptial agreements.
I wonder how many couples go without sex because they can’t decide who will sleep in it. This probably results in both parties forgoing actual sex in exchange for mutual masturbation, but then both parties would have a wetspot to sleep on, which would solve the “who gets to sleep on the wetspot” argument. It’s probably been a topic on a few Jerry Springer episodes too.
Belle and I are already jockeying for position and we’re months away from it being an issue at all. She claims she drew short straw last time although I contend the wet spot was actually in the DMZ (de-militarized zone). The usual contentions are that women bear children, menstruate, and usually sleep on the wet spot whereas men only occasionally get the wet spot. I suppose I could be a gentleman about it. Laying a towel down over the wet spot is like putting your jacket over a mud puddle for her. I’m sure PajamaThief* will convince her i’m unworthy if I don’t concede on this one. Sometimes ya just gotta stand up for whats right so like Kevin Costner in that dog of a movie Waterworld I continue my quest in search of Dryland once again. 
PajamaThief = Belle’s gal pal who has commandeered my beloved pajamas bottoms that Belle tricked me out of…not that it took much to get me out of them.
