Something similar happened to me actually. Before I came out, my mom was always saying how I was going to start wanting to go to parties and meet boys, and have a boyfriend, and I'll be obsessed with boys, and all that stuff. While I was sitting there laughing my ass off because even though I'm bi, I still seem to be more attracted to girls.
Recently I saw a screenshot of a tumblr post. In the image below, it covers a few points as to why switching from LGBT to SAGA is a really good idea. Overall, I totally support this and think it's pretty cool
