People discover their sexual orientationwhether theyre heterosexual, homosexual, or bisexualat different points in their lives. They discover it when they're children, teenagers, or even when they're adults. So, your friend isnt too young to know that shes bisexual.
A good indication that people know their sexual orientation is when they feel comfortable enough to tell others, like friends and family. So, if your friend told you that shes bisexual, then thats how she wants to identify herself. And you need to respect her and feel honored that she trusted you with this information.
Now, about any possible attraction to you, thats something youll have to talk with her about. But just because shes bisexual doesnt mean shes attracted to every single girl or woman she meetsincluding you! For instance, heterosexual girls arent attracted to every single guy they meet. Attraction is an individual thing; it happens on a case-by-case basis.
Since your friend wanted you to know about her sexual orientation, you can certainly ask her about it. She may want to talk with you, too. You can ask her what being bisexual means to her and if she thinks it will change your friendship. Ask her anything you want to know!
