Is this asexuality or not?

Hello everyone, I've been trying to understand me sexually, and it's been a rough journey so far.

To clarify I'm 18, I've been questioning my sexuality since I was around 13 or 14.

I thought i was bisexual, then gay, then asexual, then gay, then bisexual, then asexual now.

The thing is, I used to get hard on guys and to lesser degree girls, it remained this way until i approached 18, where i gradually feel like I dont really find myself "willing" or even "interested" in having sex, i do see hot people around and i do *sometimes* get hard on them but I wouldnt want to have intercourse with them. I personally watch pornography and dream but i dont have an urge to live them in real life because i just dont feel sexually thrilled or attracted to do that in real life.
