At age 6 or 7 I began questioning if I should have been born a girl. My hair grew long and people often mistook me for a girl, even into my 20s. Before my teen years, clothing didn't seem to matter, but it became important at around age 14. It started with wearing things of my sister's friend, who lived with my sister, mother and I. The friend was my size and used to joke that we could "share" each other's jeans. 🙂 Wearing women's clothing and underwear just continued from there.... I'm now a young 50.
