"Zeke" grew up in a girly world. Mother had a lot of female friends and a lot of those friends had daughters who "Zeke" would grow up playing with. In school, he just naturally gravitated towards being with the girls. In high school, "Zeke" shared that he wanted to try crossdressing with his pretty much all female circle of friends and they helped him become "Zakera". There was some mocking at first, but that died when "Zakera" was asked to the prom by the Captain of the football team. The relationship did not last, but "Zeke" grew confident and became quite the seductress as "Zakera" over time.
