I agree with submissivedoll, you don't know until you try.
I would, as she said start with small thinks, vanilla kink as I know it as. Biting, light spanking, think Ann Summers sex toys and you will get the idea (Hopes there is Ann Summers in Houston).
My advice would be that if it is something which is on your thoughts, and something you are seriously interested in then it is already a part of you. Even if you find after a while it's not for you, it's best if you let them know and you can then begin the essential communication part.
Good luck, let us know how you get on in whatever you choose to do.
