First high school date tips?

I'm a junior in high school and I've been friends with this senior girl for a while now. In the past year, she's really started being friends with me, walking with me to most of my classes and hugging me whenever she sees me. I always thought she might have feelings for me (not trying to sound naive). A few days ago, one of her close friends (girl) who is also my friend informed me that I should go out with her and that she was in to me.





I'll admit, I have very little experience in the dating world, other than one girl in middle school (that didn't last). However, I know this girl doesn't have very much experience either. I am attracted to her and I think I want to go out with her.





Here's the negative side. My brother, who is a senior, knows this girl and is always making fun of her and the way we hang out so much in school. I know it shouldn't matter, but he kind of embarrasses me. Also, since she is a senior, our relationship would probably be over when she goes to college. I don't want to get intimate with her and then break her heart. I hope we could remain friends. Also, I was thinking of bringing her to see that Twilight movie, but I won't see her until the monday after thanksgiving. She'll probably have seen it by then. Also, I don't want to make it look like I'm asking her out just because her friend told me to. I'll probably wait a while.





My question is: When and how do you think I should ask her out?First high school date tips?
First off, don't worry so much about dating. You should just try becoming friends with as many people, including girls.





Approach them confidently, but not aggresively. Be yourself. If your shy, that's fine. Start slow. You can always strike up a conversation about things that you have in common (like classes, teachers, weather, sport teams, ect)...Or compliment her. As for your hair, it depends. I personally like it when guys have a clean crewcut. But thats just me, wear your hair how you like it. Be kind, talkative (but not self centered), and positive. Don't shove yourself on someone though, be casual while still hinting that you want to get to know them. Like talking to them daily.





That's all really, relax and enjoy highschool. Don't get caught up with revolving your entire year around trying to get a girlfriend.
