Not the kind of amnesia where you wake up next to somebody and can't remember the night before. Well, sorta. But not because of beer, you drunk. It's a rare event where the act of sex causes amnesia - you, essentially, fuck until you can't remember what day it is. It's all fun and good while it's happening, but for the rest of us our memory comes back; for others, not so much. Not only that, but the article brings up another scary term: "coital headaches." Jesus Christ, it's like your crotch is doing it's best to kill your brain, and that's scary.
