Does this make me bi?

When i was young like 9 years old i was a tomboy and i liked my girl cousin i dno what it was but she was so nice and sweet and i had a soft spot for her i use to think about kissin her n stuff. And she got a boyfriend and i was so upset anyway i moved on when i hit secondary school never liked any girls just boys now im 16 and i think i like my cousin again? I dnt no what it is just the connection she's a really nice person she's also a social worker. I had sexual thoughts about her before and its really awkward. I also liked my uncle when i was 13. What is this?
