I have decided condoms are literally the bane of my existence, I got a girl back both naked in bed asks if I have a condom, yeah sure its erm ..... errr ... erm cue 2 minutes of condom hunting based mood killing.
Now every pair of trousers I have has a condom in, the draw next to my bed does and the wooden slats under my bed have one in (for houdini style condom appearance lol).
Buy them in bulk, even if its just so you can see the look on the cashiers face when you buy 28 condoms and a pack of beers (be sure to drop "Quiet night in

")
