You browse around your area for girls your age, then send them nice messages. Like...
"Hey how are you? My name is ____. I'm <Age> years old, and I live ______. You sound like a really great person, and I'd be honored to take you out to dinner sometime! What do you think? ;)"
Something like that. Short sweet and to the point.
Now if you KNOW for a fact, the girl is a whore, say something like... "Let's do dinner, and then do you." ROFL.
But seriously. Try the first one.
