I need an opinion...

So I'm pansexual (I am okay with being in a relationship with anyone, no matter how they identify) and I'm in a straight relationship, but I'm wondering about something. I haven't come with him yet. Sex with him is amazing and fun, but I haven't actually reached orgasm with him. Now, I've been in a relationship with a girl before and I came with her. She was fingering me and hit just the right spot and FIREWORKS!!! It was awesome. Does that mean maybe I'm actually lesbian? Or do you think maybe she just got lucky and my orgasm had nothing to do with her being a girl? Thanks 💕💕💕
