There was a news article on military members that get hit with IEDs that said the majority of them that were on the battlefield and suffered an IED hit and their penis was gone, they signed waivers to let them die there on the spot. Something to think about.
Me? I don't think I could, but like in the movie 'Born on the Fourth of July,' I could make it happen. Probably with copious amounts of liquor drowning away in my own piss, puke and tears.
