I'm extremely confused about my sexual orientation and I'm not sure what to do. I've only ever had a crush on a girl but I've had multiple times where I've had feelings of attraction to both men and women. I've never been in a relationship, partly due to social anxiety, so this just further confuses me and I have no idea what to do.
You could be bi but there's no rush. You should take your time to explore your sexuality. There's no hurry. Sexuality is fluid can be complicated. I know some people who are in their twenties and are still questioning. Even I didn't get a serious crush on a single guy for three years after I've realized that I was gay.
This was the first girl but I found out she was gay before I even got to think about telling her how I felt.
