Idk my sexuality

Ok so im 15 and i have a boyfriend who i am very much in love with. But i cant help but feel confused about my sexuality. When i was younger about 10-11 i would practice kissing with my best friend and i dont remember hating it, so does that mean that i liked it? I am open to the idea of it maybe not something more but i have thought about dating a girl if i cant find a guy or dating a girl is a better option according to my feelings what should i do?

P.S. the most I've ever done with my bf is a peck on the lips

I dont know why you need to know that but there it is😐

P.P.S. he's really cute and sweet and he makes me feel safe
