Confused whether lesbian or not.

So.
I've been dating this guy for a few years. Everything was pretty perfect with him up until the point we had a threesome with my best friend.
We've always been very loving and close to each other , but now i look at her in a new light. I get disappointed when i can't see her. Our cuddles and hugs feel different. I can't stop thinking about her.
And oh my god i want to take that girls clothes off.
Now i wanted to figure out whether i have these feelings for her just because of the threesome , or because i'm actually.. Well gay.
Please help. This has been plaguing my mind for far too long.

 

No. You are dating and sleeping with a guy.
Being attracted to a female doesn't qualify you as a lesbian, at all, period.

 

being a lesbian is far, far more than just wanting to have sex with a particular girl.
You just experienced a "new toy"

You'll know the answer to your question in a few years - as for now, just ignore labels and enjoy what comes your way.

 

Yep. Being a lesbian is not just about physical attraction. It's wanting to spend your life with a woman.

 

You really have to compare the intensity of emotions, what does it feel like being with him in comparison to being with her. I have been with guys in the past, I have lived with a guy for four years, an then I slept with a girl, and it blew my mind. I can find a man attractive and kiss him, and get an orgasm, and it all feels very mechanical and shallow. When I find a girl attractive, it's a different experience, I am on an emotional high, when I kiss her it's a supernatural feeling, and when I make love to her is a spiritual act.
