EDIT: Woops, sorry, thought you were talking about a high school gym situation. If it actually is I hope I helped, if not, ignore my post -- free bump I suppose.
I'd like to hear more about your gym situation -- the great thing about gym is that it's a great way to start giving kino since you have an excuse. Also, most AFCs actually HOLD BACK their kino in gym because the girls have less clothing on and they're too nice to touch them.
This is where you come in. If you're playing a sport don't be afraid to make physical contact. Neg her, telling her that she "plays like a girl," whatever. Push-pull is powerful -- tell her a funny DHV story or routine, then run off and tell her that you want to go hang out with your "wayy cooler friends

"
Just be generally playful, man. Sarging in gym is probably easier than sarging anywhere else in HS.
Good luck, I know you can do it.
