Is it normal i want to fuck/love my bestfriend? my same-sex friend?

I started a new school a few months back and everyone is really nice there. I was bullied at my last two schools so the equivalent of 4 years angry at the world. (like every angsty teen) It's not like i didn't have friends there but i didn't have someone so simaler to me. It's like we're clones, twins, the same entity really. we like the same things and get illnesses at the same time.ect.ect. we're REALLY alike!
So anyway one time I was really getting into some hot well deserving 'Me' time and I thought of her. well moaning an 'OOOOOOhhhhhhh'. whitch pretty much confused the heck out of me and stopped my session all together. After this event i looked at some 'material' to see if i was actually
interested. I was. I also started to notice Women in general in my all female school.My dirty jokes also started to take a more Flirty approach to them I even almost ran my hand through her hair. This doesn't really feel like a crush but i keep imagining making Her feel good and the thought of giving her multiple orgasms sets me a throb.And now ive started to think of her making Me feel good. We have a Bisexual (woman) Friend and some of the ladies at my school have even had a threesome together.

Upon finding someone so like yourself is it normal to want to fuck them sencless?
