TOKYO — Master Sgt. Marc Maschhoff revels in the turns his life has taken in the last year.

Last summer, Maschhoff had to keep his sexuality a secret or risk being kicked out of the Air Force.

On Monday, he was happily introducing his boyfriend to diplomats and politicians from around the world as the U.S. ambassador to Japan held a reception in honor of Lesbian, Gay, Bisexual, Transgender Pride Month.
