The Croy Cycle Series by Louis Flint Ceci

Last year, Mally Jacobs was the weird kid in school, but that was before he spent a summer in New York, witnessed the Stonewall Riots, and kissed his first boyfriend. Now he's back in Oklahoma, calling himself "Jake," and using his new-found basketball skills to impress his friends and earn a name for himself. But the small town of Croy is a far cry from the freedom and daring he tasted in New York. Can he find a place for himself while holding on to a secret?
