Bi - she's amazing but.. why😢

So im 18 if thats an important information:) and i've known about my bisexuality for quite some time now.

So.. for some reason I still have some difficulties with women. I'm a coward i'm not even gonna lie haha a lot of them don't know about their sexual prefrences just yet and i dont want to push them into any regions where they arent comfortable.

I flirt with them and geniuenly adore them. And they except it and flirt back but it doesn't goes any further from that. Is there something wrong with the way i flirt.. i think they just think that its a friend thing or am i fooling myself that they're flirting back.. i suppose its just to early and that not even i know how to take it all further.. but i dont know haha

Do any of u experience this? I think its just a high school thing, but do u get me? Its just sooooo frustrating i just cant take my eyes off her.. shes amazing..
