Humans live in constant fear of disease, and there's no disease scarier than an STD. (Well, if your primary concern is getting laid ever again, anyway.) Paranoia is natural, especially 'cause so many STD symptoms overlap with relatively harmless maladies.

1. Cold Sores
You sloppily made out with that chick in the corner of a dive bar. Now you've got a bulging red blob on your upper lip. It's HERPES, right? Well, there's a difference between type 1 and type 2. Grab some Orajel--it's not the end of the world.
2. Ingrown Hair
A giant bump on your lip is one thing...but on your junk?! You pray it's a zit, but the Clearasil sure ain't working. You're about to visit the free clinic when you notice a short-and-curly under the skin. Be more careful next time you manicure that lawn.
