Well any relationship can be a risk drake. I just wanted to add one point. I believe that there are two types of poeple in this lifestyle. Those who chose it, and those who have been chosen by it. In other words, D/s is a sexual orientation, and not a choice or fun flavour for some. I like to term those who have this orientation as hardwired. If you find yourself in this category, from my experience, hardwired folk tend to get along better with hardwired folk, and I wonder at such a young age, if this girl knows if she is hardwired or not. If you are a hardwired D/s person, and you come to find out, later in years as the two of you have been together, that she just likes to flavour the relationship with some fun bedroom d/s or her d/s likes were just a curiousity, it could be a very tough time for you both.
It would seem to me, that folks that are a little older, may be gravitating to this lifestyle out of need, and not necessarily out of want, and your chances for a match may be better.
Or... everything i've said is a bunch of crap and she could be the woman of your dreams. LOL Does this help?!?!
Good luck with it.
