My advice is to focus on your studies. Because any relationship requires time and effort. And it will definitely eat into your education.
At your age, my dear girl, I know it's all about experimentations and trying out new things. But are you able to handle the emotional stresses that it may bring about, and not let it affect your schoolwork?
I know I sound like an old uncle. When I was at your age, I used to think these grown ups are so annoying. You may find me annoying too. But that is because I care. This is what I came to learn as the years went by.
As long as you can handle the stresses, go right ahead. But breakups MIGHT be inevitable and can you handle the situation?
Pardon me for being so blunt about this. But this is something you have to know. And perhaps this might be something you need to learn by yourself. I wish you all the best. Don't forget your studies.
