But I'm a Cheerleader(2000)

A comedy of sexual disorientation.

Megan is an all-American girl. A cheerleader. She has a boyfriend. But Megan doesn't like kissing her boyfriend very much. And she's pretty touchy with her cheerleader friends. Her conservative parents worry that she must be a lesbian and send her off to "sexual redirection" school, where she must, with other lesbians and gays learn how to be straight.
