“One of my gay friends was telling me how he realized he was gay, and I found myself relating to everything he was saying. Before that, I thought I was asexual. I knew I wasn’t into girls, but had never really seriously contemplated whether or not I was into guys, perhaps because I was afraid of the conclusion I’d reach, so I just settled on thinking I was asexual.”
“In hindsight, I’d always been into guys; I just misinterpreted all my feelings of attraction as feelings of jealousy. I’d see a hot guy and tell myself that I really wanted to look like him and that that was why I couldn’t stop staring. It made sense at the time, even though it sounds absurd in retrospect. During that conversation, the realization that I had been in denial for years just hit me, and I knew I was gay.”
