2. Never EVER Trust the Other Person to Come Prepared
Welcome to the 21st century people! Stop thinking everyone else will have the proper material. Chances are if they have a condom in their wallet, it dates back from their High School prom, and is thus ineffective. You should always have a full stock of condoms and lube in your apartment because you never know. It's a lot cheaper than child support! It's also not only about the protection against the B word. This city is swarming with other special guests that maybe you don't want entering your system if you catch my drift. Recent research showed that Gonorrhea has become resistant to the antibiotics. So come prepared for the party, no one likes a tourist.
