I feel there might be a less confusing way to phrase this sentence about a transgender teen: "Ayden grew up a tomboy and in sixth grade thought he was a lesbian."
Maybe this would be a good opportunity to write a sentence without pronouns, newspaper people. Because you can be correct and still ridiculous.
Also, I really really, really dislike the word tomboy. It implies that sports, hammers, trousers, and playing in the mud are at best non-normative and at worst transgressive for little girls. What the actual fuck, society?
(Just to be clear, I am suggesting they write "Ayden always gravitated towards sports and construction equipment, and eventually became aware of an attraction to girls." OR WHATEVER. But 'he was a lesbian' is always going to sound ridiculous, which distracts from the story. Much like reading 'she always wanted to wear dresses' about a transgender teen who previously identified as or was assigned male, it makes the reader confused rather than thoughtful.)
