Too young to know?

So I was cooking dinner the other night and chatting with my daughter about her day. After a little time of small chit chat she asks for my opinion on something. So the beginning of the conversation kind of went like this.
Tamara: so ummm , yeah well it's, okay so we were talking at school today and ummmm
Me: What honey? what's up
Tamara : okay so do you think we're too young to know if we're gay?
Me : ummmmm.....well I'm not sure*insert 10 second pause here*
So my thought process after her question went something like this.
Really?? How the hell did I miss that? I thought she liked guys!! Way to go Tracy, you're so not the observant mother I thought you were. LMFAO....okay smile and answer the poor girl.
Me : I think that at your age you would know what you're attracted too right, so you're attracted to girls more then boys?
Tamara : lol.....it's not me mom, I definitely like boys.
So I'm not gay but I do know what it feels like to be attracted to the opposite sex. Attraction is attraction whether you're gay or not...so when did I first notice boys? Was it then that I knew what my sexuality was or was it later on? Okay that was too long ago so I need to stick with what I do know. I told her that kids her age may not know if they're "gay" but they know what their attracted too. If they're attracted to the same sex then it's a starting point perhaps to their sexuality. In my opinion it would be hard to say at this age with no real connection physically or emotionally to the other person to know if you're gay. I mean I have been attracted to women too but the idea of being intimate with them was never a thought for me. So she explains to me that her friend is confused and is attracted to both boys and girls but likes girls better. What do you say to that? You know that she's going to go back to her friend and talk to her about what you say. Ughhhh....
 So I did the best I could, I told her that her friend needs to be careful and not label herself. That her friend is still young and doesn't need to find herself in 30 seconds. Running around one week with a girl and the next with a boy is only going to attract unwanted attention and the rumours will begin. There is nothing wrong with being gay of course but it's not just something you say for attentions sake. Gay people have had to fight for respect, understanding,acceptance and the right to just be treated normal with the right to not hide what they really are inside and without fear of being bullied, ostracized, excluded, beat up or left out of participating in life. I also told her that her friend should speak to her parents if they're open to discussions but sadly if they're not, there are adults that are. I'm so thankful that Tamara will talk to me about anything and comes to me for advice. I just don't know if what I said was enough or if I even came close to handling the situation correctly. I just pray that it helped. She said it did but....is she too young too know?
