I’m been straight my whole life but now I’m confused

Ok so, I’m 21 ( I’m a girl) and around 4 years ago I started to read manga ( yaoi, shoujo, slice of life and not really interested in Yuri ).Recently, I’m getting this feeling of talking and being more intimate with a female friend of mine ( we are not that close, but during quarantine we started to talk more). And I don’t know what to do, it’s the first time I’m thinking of a girl this way. I was always attracted to men til now.

So that makes a bisexual, right?
Have you guys experience something similar?
