I suggest that rather than going out and finding people who already play, you start a group of your own.
Every gaming group has its own sort of mini-culture, built around the preferences, attitudes, and skills of the players, and each has its own in-jokes, etiquette, history, and interactions.
If you try gaming with a group whose mini-culture bugs you, you aren't likely to enjoy the game. Pencil and paper RPG's are very collaborative, making it important for there to be some agreement amongst the participants, and the atmosphere, history, and "hanging out" stuff is just as important as the rolls of the dice.
You only need to gather three people--one to run the game and two to run characters. Whoever is the most interested in RPG'ing should run the game because it takes the most effort: DM's have to read the source material, help everyone build characters, and then set the scene. It's their job to tell people when to roll the dice (and what dice to roll, and how many). They get final say on what that dice roll means and what happens next.
I've played with my younger brother (who's seven years younger than me) and my son and had a blast. I've also gamed with my husband's parents. You don't have to limit yourself to like-minded people of your own age or usual social set. You might be surprised how easy it is to put a group together. Just ask around and see who wants to try a pencil and paper RPG night--although, you might avoid mentioning Dungeons and Dragons to some people, because there really has been an attempt to demonize it, as has been demonstrated upthread.
For that matter, the White Wolf games that I mentioned above are a little simpler in rules set and a more interesting read, in general, than the D&D stuff. The only problem with them is that it seems the organization of the books is deliberately obtuse, so that the DM has to read
everything before they can start a game. But they might be easier for beginners, and they have a wide enough variety of "flavors" to interest just about everyone.
Just to get started, if you've never gamed before, you might want to "run a module". A module is a pre-made game, where everything except what the player characters do is already set. There are maps, and background info for the DM to read out loud, and the traps/monsters/encounters are already detailed out for you. It can be fun--but in all honesty, I've been gaming around 15 years and have run through a module exactly four times, one of which being my very first game.
*Whew* I guess I'm more of a dork than I realized...I don't know when to shut up about gaming, apparently.
I think I'll wait for the OP to come back before posting again...
