Ease Me In (The more guarded approach):
I'm starting to think about all of the ways I need to prepare for college in the next couple of months. I am 100% committed to being responsible, finishing my degree and not letting anything get in the way of that. I'm not sexually active right now, but I was wondering if we could talk about what you would think of me getting started on a birth control method now, so that I am protected in case I meet anyone when I'm at school?
Just Give It to Me (The no-nonsense tactic):
I have looked into all the different methods of birth control and would like to talk with a health care provider about getting [method] before I go to school. I'm not sexually active right now, but I do not want to get pregnant while I'm in college. I've done lots of research and I think this will be a great option for me to start now.
