Hey, I'm closeted as well and am in love with a girl. I still don't know if I'm bi or pan too. I don't really have many tips seeing I'm in the same situation. I just wanted to post this to let you know you're not alone.

Well, you're going to have to be more specific in terms of your attraction and you liking a girl and not being attracted to men.
In other words: would you ever have sex with a guy? How about a girl? Or maybe you wouldn't have sex with either of them? I know you're 14 so maybe sex isn't exactly on your mind, but still something to think about.
I identify as demisexual panromantic (just Google those terms if you don't know). I'll tell you how I figured that out if you think it'll help you?

I am 20 and im still very confused about my sexuality. My way of discovering what i am is just “try and see”. I am definitely attracted to women but i dont know about guys.
I had a boyfriend once but he was trans so it was kinda different (i hope this isnt transphobic).
But the only person i really love(d) is/was my female friend.
And to add even more trouble i am genderfluid so labels are even harder to use.
So what i was trying to say is you have your whole life to figure this out. And just try different things and see. I have a joke with my friend that we will come out on our deathbed because it will take so long. I hope this helped in any way :)
