how to determine asexuality?

Rose
I feel like I could be asexual, tbh. the first time I had sex it was alright but I never got any actual pleasure from penetration and he never got me to orgasm from oral. porn is enjoyable for me and I can make myself come, but being with someone else doesn't bring a huge sense of pleasure for me. I've been with my bf for a couple months and the idea of having sex with him seems kinda weird, not awkward, but just like I'm not aching for it. is this mindset because it was my first time so it wasn't the most enjoyable it could be? should I keep fuckin anyways or listen to my brain?
