Sounds like a great way for your penis to catch a cold if you ask me.
I'm pretty sure these have existed for awhile, but you know what? The first day of summer was just a couple days ago, so it seems appropriate. Also: these short-shorts I'm wearing. "No, those are indecent." Oh why -- just because my penis is peeking out the leg? You don't know fashion! This is the $100 Bed Fan from Brookstone (Hammacher Schlemmer's less spazzy, but still VERY spazzy little brother). It sucks air (plus dust bunnies!) from floor-level and blows it between your bedsheets. Admittedly, I kinda want one, but you know what I'm afraid of? That the cool breeze at night will give me a boner. "I don't see how that's a problem." Well it is one when you still share a bed with your brother.
Thanks to Dougie, who stays cool in the summer the old fashioned way: wading in the river naked. F*** yeah -- let's play Marco Polo!
