Im 16years old, I have never had a relationship with a female, but I THINK I find females attractive, I find males attractive but its kind of faded from the past year or so, could I be bi?

It could be you are bored and curious. This is kind of typical.

Sounds like many bored 16 year olds,

So you date ( without sex of course) and see which interests you more. And when you turn 18, you can experiment with it, if that is within your moral acceptance.
