Does This Make Me Gay?

My best friend izzy from all the way back to middle school is a lesbain. Only growing up I had no idea. She came out to sophomore year. It was really hard for her and I was proud of her and accepted her right away. She's my very best friend in the world!
I admit the first few sleep overs after finding out where awkward but I knew that was just being stuppid. Izzy after taught me to use tampons and has seen me change countless times and since I am not a homophobe I just refuse to be weird.
But then at sleep over she'd end up in my bed kind snuggling me and that never happened before but again platonic girls friends that all time right? I didn't want to be weird about it.
Then last month were watching a movie at my place and my dad had the AC cranked and it was cold in the basement and we cuddled under a blanket... and again that was something we'd do before and think nothing of it but some how this time her her hand ended up on my boob. It probably was an accident but she didn't move it either. She knew were it was and liked touch it. I had no bra on and I could feel her palm on my nipple and she was teasing it. Then later on she laid her head on my chest like I was her boyfriend or something. By the end of the movie she was hugging me chest to chest and for a second before she got up i thought we were about to kiss. Inside I was freaking out but nothing sexual happened so I let it slide and ignored it.
A few nights later we where getting high together back at her room after a party we'd been at and out of fucking no were she kisses me full on the mouth with tongue. I froze. I think I was scared. I just let her kiss me more.
I think I was in shock but also high & drunk. I didn't kiss back but I didn't stop her and her hands were all over me.
"Gwen, nobody needs to know. I need you so bad. I've been in love with so bad so long, since middleschool". She whispered my ear full on making out with me fonding my bare boobs under my top and touch me all over while I just didn't stop it.
Finally said, "Izzy, you know I love you but I am not sure I can. I am not sure my body works that way. If i was a like you i'd never hold this back from you."
"Try." She pleaded... so I did. I kissed her back. I felt her boobs back. I took my top off....to give her full access and I was all in.
I don't want to make this to graphic because it was deeply personal but she taught me finger play she had an orgasm while I fingered her and I honestly felt closer to her then ever knowing i made her cum. It was incredibly to watch her orgasm under my touch. Then she went down on me.... and O My Fucking Goooness I was on fire and couldn't stop cumming. I had multiple orgasms for the first time ever! I clearly was not the first pussy Izzy has eaten... she was a pro down there!!!

They next day was awkward at first but I told her it was incredible but I am confused... I like boys and have had great sex with men. I don't look at women like I do men and I didn't expect to like this. But she said that's OK we can go slow and not have sex again until I am sure.
But she is still kissing me, holds me, touches me romantically tell me she loves me. Fuck I am so confused I am her girlfriend now? I am gay? What is happening!!!!
I am so confused and don't want to hurt her so I keep letting her kiss me and fondle my body as long as it's not turning into sex. But i know she wants more sex and is touchingme hoping ill want it too. It's true I'd love to be eaten out like that again but I am not sure I could ever eat pussy.
Am I gay but not gay enough... I'm so confused.
Help.
