Wondering if I’m asexual

I (28F) had sex with my boyfriend (28M) a couple times. I don’t know if I like the experiences, never get to finish but he did and I felt happy for him. I always end up either frustrated or sad.

He’s Christian so just doing it, I feel guilty. Before him I was sure I was asexual, never had interest in sex or even touching, it disgusted me. With him, I felt it was something meant to do between couples and sometimes I feel I was just curious but I don’t look forward to any sec advances.

Am I asexual or just confused?
