So does anyone else deal with this other than me?

As soon as I go outdoors (I live in Florida) my skin starts itching at random spots. Its not even just mosquitoes. I played a game of Humans versus Zombies at college with a friend who was really into it. I was itching almost the whole time while he literally didnt feel a thing. Maybe we have different diets or genes?

What can I do to get more used to the /out/doors?
