Honestly, dude, +100 points for being 11. I would have guessed 14-16.
I personally don't think there's any point in getting into relationships before highschool. Aside the dumb, obvious facts like 100% of relationships that start prior to highschool fail, they're literally just a waste of time. Going 'far' for you would be kissing, that may be exciting to you but it ain't worth all the work you'd have to put in to get there. I know you don't want to listen, but I'm almost sure you won't ask her out. I don't think eleven year old me would feel comfortable asking her out, and I could walk around proposing to random women for an hour straight.
