Ok, I seriously need help.

Okay, I think i can give wewe some advice.

wewe pair are 14. And wewe both had/have BF, meaning your friend may be Bisexual. But at the same is at the age of 14, everything is soo new, wewe want to experience everything now and then.
If your acatually worried that she may have a crush au 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 wewe get horny who do wewe think of without any control on the thought. Do wewe think of her kiss,not because it was so shocking but because wewe want to do it again and again.

Also, experimenting with Marafiki HAPPENS ALL THE TIME. I know me and my best friend fuck every sleepover, single au 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 wewe picture yourself being with her, au does it upset au gross wewe out.
Since the kiss, have wewe been thinking about what it be like if another girl kissed you?

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

But if wewe 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.
