Ok, I seriously need help.

Okay, I think i can give te some advice.

te pair are 14. And te both had/have BF, meaning your friend may be Bisexual. But at the same is at the age of 14, everything is soo new, te want to experience everything now and then.
If your acatually worried that she may have a crush o feelings for you, don't stress, because no matter what age a woman is, they will at least once feel something for a another woman. But being young means nothing's permant.
Follow your heart. What does your sex-drive tell you. When te get horny who do te think of without any control on the thought. Do te think of her kiss,not because it was so shocking but because te want to do it again and again.

Also, experimenting with Friends HAPPENS ALL THE TIME. I know me and my best friend fuck every sleepover, single o not . (we've cheated with each other :P)But still no strings attached.

Close your eyes, and imagine yourself holding her hand, standing behind her and holding her waist, brushing her hair, looking at her lips, embracing in the photos. Can te picture yourself being with her, o does it upset o gross te out.
Since the kiss, have te been thinking about what it be like if another girl kissed you?

But being at the early stages of teen means that te beleive and want to experiment and be unique, but time will reveal wheither where your cuore lies. Don't stress yourself out, and dont make your friendship awkward.

But if te want to talk to her, just talk to her, she's still your friend right, talk to her normally. She kissed you, so It's not like its going to be a shock to her.
