Still waiting for lockage. 
Wow, someone must think they got balls that clank.

Now, to the point..
Ovbiously, nothing anyone says will change your mind, Charismatic. Truth is, no matter how much "charisma" you work on this girl, it's just not going to work. You might assume that she might not make your life a living hell, but trust me, women are devious. A girl her age, probably being under the age of consent, has all the power in the world to make your life a living hell. You're an adult as well, that is if you're in the US. Once you're 18, you're an adult in the law's eyes, and her word usually is golden if she's good enough to pull it off. I've seen this happen to three teachers in my old hometown,
Why am I convinced that you'll still do it? You said it yourself:
Hormones.
You're thinking with the wrong head here, and no, I'm not saying you want sex from the girl, but you honestly are letting the testosterone take over instead of common sense and logical thinking. Common sense meaning if she's avoiding you, or expressed disinterest when you gushed to her, well then it's pretty damn safe to say she isnt going to accept a kiss. It honestly does sound like you're trying to have your way with her, and since it seemed like you didn't understand it when Ace said it, it means that you're forcing this kiss on her. Even if it's supposed to be a "suprise" move, it's still forced, because common sense tells ME that she's UNINTERESTED.
Expect a slap, and DON'T expect sympathy from the board if you DO get slapped. And if you Dont get slapped, hey, more power to ya, but I'm sure there'll be a 3-part harmony chorus of "TOOOLD YA SOOO" from the board if you tell us it didnt work out the way you wanted to.
