Phoenix, you are in college. Forget about dates and restuarants. Take her to the cafeteria. Take her to a party and get her drunk. Don't bother pursuing a relationship until you've had some sexual experience. You probably need the confidence that will come with it.
Don't feel like you aren't being a gentlemen, or that any girl that is willing to fuck is a slut. These are the last years in your life where it will be this easy to get pussy. After college, most girls are just gold-digging whores.
