Hey, I didn't figure out I was a lesbian until I was in my mid 20's. If someone had asked me at that point I'd have said there were no clues and hints up until that point that I was anything other than straight. Since then and since accepting my sexuality and coming out etc, if I look back now there are things I can see that kind of were a bit like hints but at the time I didn't see them. What made you question your sexuality?
Let's see... I hadn't ever been into guys as a child, and I had a huge crush on one of my friends. I didn't really know being lesbian was an option when I was a kid so I kinda just figured I hadn't found the right guy. Eventually, I decided that I wanted to be with girls because that is who I am. I am still in the closet, but I at least know that I can be honest with myself.
