A lot of effort goes into manufacturing condoms that are comfortable and effective, but that doesn't do anyone any good if no one wears them. So some well-intentioned goober has decided to slap QR codes onto condom wrappers so you can check in every time you, uhh, unwrap one.
WhereDidYouWearIt.com tracks all the places you have sex, so long as you scan the code on the condom wrapper each time. The hope is that it'll get young people to actively use condoms more often, but it's also great because this is absolutely something you want a permanent record of on the internet, forever.
