That excitement before trip #1... enjoy it.
Like has been said, there are plenty of good guys willing to give tips, even take you around to show you some of the places. Remember, a drink or even lunch is a nice gesture of appreciation for anybody who takes time out of their day to show you around.
Also, a word of caution.... many guys over-do it on their first trip. When I say over-do, I mean girls, alcohol, even drugs. Always stay in control, you'll have a better time and be safe. Also, avoid being on the streets late at night. Taxis everywhere after dark.
