Everyone matures at different rates. It's true that most people experiment in high school, but that's not always the case. I dated mostly girls in high school but now prefer men over women because I realized that what I wanted could not be found in women.

However, my best friend who is the same age as me is now just starting to experiment with women and is telling me that she is having crushes on me, and we're both out of high school.

I would recommend you try looking for what you want in men and women and you would find that they are likely to be completely different.
