I heard a farbrengen given to girls your age. I can’t sum the whole thing here because no one likes king posts and it takes much time to write up.
Main points: our natural instincts are good and wonderful, and need to be guided to the appropriate place. Let’s say a girl is going to fast for her first time: she might start panicking, feeling she won’t survive the fast. Instead of ignoring and fighting her feelings, she can realize that yes, if she doesn’t eat for three days, she could die, but the fast is not 3 days so she’ll be ok. Working with your feelings instead of fighting them. And putting them in perspective.
In this case, it’sa wonderful attraction Hashem created to the other gender. It helps us marry and build loving stable homes. But there’sa time and place for it. And it needs to be the right person too.
Any of our natural instincts are powerful and therefore can be hard to fight. Hashem gave them to us as a gift and we need to use the brains Hashem gave us to make sure the gift is being used the way it’s meant to be, because otherwise it can be destructive.
