Would they go into my body...? Im not sure I like that idea... Id just assume I left myself asleep somewhere while I galavanted. I'd definately have to be a bloke, i wouldn't mind trying out sex from a male POV. And maybe a wank too. Maybe I could just be the boyfriend for a day... but Im not sure Id want to have sex with myself, plus he's addicted to warcraft and I generally know what hes up to for the most part. I dont think Id want to be anyone I know (And like) to be honest I wouldn't want to nosy into their personal lives that much. Maybe I could be Michael Fassbender or Matt Bellamy

Or I could just be someone I don't like and be an absolute arsehole and generally just show them up. Im not sure I hate enough to do that too at the moment though, so id have to go with the first, willy related option
