If you're still in highschool there is a good chance you won't be getting laid. Don't worry about the virgin thing for now.
You have to start somewhere, why not here? The more you get out the easier it gets.
People will try to force you to drink, it's not a hard thing to do, and chances are you'll like the feeling after a couple of drinks. You being a light drinker, will puke quite easily. Try not to have more than 1-3. Pace yourself. Nothing more pathetic looking than puking all over someones house.
Go to the party. Don't be nervous. Being nervous will kill you. Figure out what works for you. Stay calm and collected. Easy to say, hard to execute. It gets easier. You can't meet people if you staay inside all day.
EDIT: Alot of people go to parties just to pick fights. If you don't want to fight, don't be a smartass.
